+```
+
+The resource plugin is meant to allow users to limit or reserve resources for a given app/process-type combination.
+
+## Usage
+
+By default, Dokku allows unlimited resource access to apps deployed on a server. In some cases, it may be desirable to limit this on a per-app or per-process-type basis. The `resource` plugin allows management of both resource "limits" and resource "reservations", where each resource request type has specific meaning to the scheduler in use for a given app.
+
+> The meaning of a values and it's units are specific to the scheduler in use for a given app. If a scheduler does not support a given resource type combination, it will be ignored. All resource commands require an app rebuild or deploy in order to take effect.
+
+Valid resource options include:
+
+- `--cpu`
+- `--memory`
+- `--memory-swap`
+- `--network`
+- `--network-ingress`
+- `--network-egress`
+
+Resource limits and reservations are applied only during the `run` and `deploy` phases of an application, and will not impact the `build` phase of an application.
+
+### Resource Limits
+
+When specified and supported, a resource limit will ensure that your app does not go _over_ the specified value. If this occurs, the underlying scheduler may either cap resource utilization, or it may decide to terminate and reschedule your process.
+
+Resource limits may be set via the `resource:limit` command:
+
+```shell
+dokku resource:limit --memory 100 node-js-app
+```
+
+```
+=====> Setting resource limits for node-js-app
+       memory: 100
+```
+
+Multiple resources can be limited in a single call:
+
+```shell
+dokku resource:limit --cpu 100 --memory 100 node-js-app
+```
+
+```
+=====> Setting resource limits for node-js-app
+       cpu: 100
+       memory: 100
+```
+
+Resources can also be limited on a per-process type basis. If specified, this will override any generic limits set for the app.
+
+```shell
+dokku resource:limit --cpu 100 --memory 100 --process-type worker node-js-app
+```
+
+```
+=====> Setting resource limits for node-js-app (worker)
+       cpu: 100
+       memory: 100
+```
+
+#### Displaying Resource Limits
+
+Running the `resource:limit` command without any flags will display the currently configured default app limits.
+
+```shell
+dokku resource:limit node-js-app
+```
+
+```
+=====> resource limits node-js-app information [defaults]
+       cpu:
+       memory:
+       memory-swap: 100
+       network: 100
+       network-ingress:
+       network-egress:
+```
+
+This may also be combined with the `--process-type` flag to see app limits on a process-type level. Note that the displayed values are not merged with the defaults.
+
+
+```shell
+dokku resource:limit --process-type web node-js-app
+```
+
+```
+=====> resource limits node-js-app information (web)
+       cpu: 100
+       memory: 100
+       memory-swap:
+       network:
+       network-ingress:
+       network-egress:
+```
+
+#### Clearing Resource Limits
+
+In cases where the values are incorrect - or there is no desire to limit resources - resource limits may be cleared using the `resource:limit-clear` command.
+
+```shell
+dokku resource:limit-clear node-js-app
+```
+
+```
+-----> Clearing resource limit for node-js-app
+```
+
+Defaults can also be cleared by leaving the app unspecified.
+
+```shell
+dokku resource:limit-clear
+```
+
+```
+-----> Clearing default resource limits
+```
+
+### Resource Reservations
+
+When specified and supported, a resource reservation will ensure that your server has _at least_ the specified resources before placing a given app's process. If there a resource exhaustion, future rebuilds and deploys may fail.
+
+Resource reservations may be set via the `resource:reserve` command:
+
+```shell
+dokku resource:reserve --memory 100 node-js-app
+```
+
+```
+=====> Setting resource reservation for node-js-app
+       memory: 100
+```
+
+Multiple resources can be limited in a single call:
+
+```shell
+dokku resource:reserve --cpu 100 --memory 100 node-js-app
+```
+
+```
+=====> Setting resource reservation for node-js-app
+       cpu: 100
+       memory: 100
+```
+
+Resources can also be limited on a per-process type basis. If specified, this will override any generic limits set for the app.
+
+```shell
+dokku resource:reserve --cpu 100 --memory 100 --process-type worker node-js-app
+```
+
+```
+=====> Setting resource reservation for node-js-app (worker)
+       cpu: 100
+       memory: 100
+```
+
+#### Displaying Resource Reservations
+
+Running the `resource:reserve` command without any flags will display the currently configured default app reservations.
+
+```shell
+dokku resource:reserve node-js-app
+```
+
+```
+=====> resource reservation node-js-app information [defaults]
+       cpu: 100

+       memory-swap:
+       network:
+       network-ingress:
+       network-egress:
+```
+
+This may also be combined with the `--process-type` flag to see app reservations on a process-type level. Note that the displayed values are not merged with the defaults.
+
+```shell
+dokku resource:reserve --process-type web node-js-app
+```
+
+```
+=====> resource reservation node-js-app information (web)
+       cpu: 100
+       memory: 100
+       memory-swap:
+       network:
+       network-ingress:
+       network-egress:
+```
+
+#### Clearing Resource Reservations
+
+In cases where the values are incorrect - or there is no desire to reserve resources - resource reservations may be cleared using the `resource:reserve-clear` command.
+
+```shell
+dokku resource:reserve-clear node-js-app
+```
+
+```
+-----> Clearing resource reservation for node-js-app
+```
+
+Defaults can also be cleared by leaving the app unspecified.
+
+```shell
+dokku resource:reserve-clear
+```
+
+```
+-----> Clearing default resource reservation
+```
+
+### Displaying resource reports for an app
+
+You can get a report about the app's resource status using the `resource:report` command:
+
+```shell
+dokku resource:report
+```
+
+```

+
+You can run the command for a specific app also.
+
+```shell

+```
+
+```

+       web reservation memory swap:
+       web reservation network: 8
+       web reservation network ingress:
+       web reservation network egress:
+```
+
+You can pass flags which will output only the value of the specific information you want. For example:
+
+```shell
+# Note the periods in the flag name
+dokku resource:report node-js-app --resource-web.limit.memory
+```
+

 The `subdomain` is inferred from the pushed application name, while the `domain.tld` is set during initial dokku configuration. It can then be modified with `dokku domains:add-global` and `dokku domains:remove-global`. This value is used as a default TLD for all applications on a host.
 
-If a FQDN such as `other.tld` is used as the application name, the global virtualhost will be ignored and the resulting vhost URL for that application will be `other.tld`. The exception to this rule being that if the FQDN has the same ending as the default vhost (such as `subdomain.domain.tld`), then the entire FQDN will be treated as a subdomain. The application will therefore be deployed at `subdomain.domain.tld.domain.tld`.

-## Switching from Dockerfile deployments

+
+## Usage
+
+### Listing Buildpacks in Use
+
+The `buildpacks:list` command can be used to show buildpacks that have been set for an app. This will omit any auto-detected buildpacks.
+
+```shell
+# running for an app with no buildpacks specified
+dokku buildpacks:list node-js-app
+```
+
+```
+-----> test buildpack urls
+```
+

+-----> test buildpack urls
+       https://github.com/heroku/heroku-buildpack-python.git
+       https://github.com/heroku/heroku-buildpack-nodejs.git
+```
+
+### Adding custom buildpacks
+
+> Please check the documentation for your particular buildpack as you may need to include configuration files (such as a Procfile) in your project root.
+
+To add a custom buildpack, use the `buildpacks:add` command:
+
+```shell
+dokku buildpacks:add node-js-app https://github.com/heroku/heroku-buildpack-nodejs.git
+```
+
+When no buildpacks are currently specified, the specified buildpack will be the only one executed for detection and compilation.
+
+Multiple buildpacks may be specified by using the `buildpacks:add` command multiple times.
+
+```shell
+dokku buildpacks:add node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+dokku buildpacks:add node-js-app https://github.com/heroku/heroku-buildpack-nodejs.git
+```
+
+Buildpacks are executed in order, may be inserted at a specified index via the `--index` flag. This flag is specified starting at a 1-index value.
+
+```shell
+# will add the golang buildpack at the second position, bumping all proceeding ones by 1 position
+dokku buildpacks:add --index 2 node-js-app https://github.com/heroku/heroku-buildpack-golang.git
+```
+
+### Overwriting a buildpack position
+
+In some cases, it may be necessary to swap out a given buildpack. Rather than needing to re-specify each buildpack, the `buildpacks:set` command can be used to overwrite a buildpack at a given position.
+
+```shell
+dokku buildpacks:set node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+```
+
+By default, this will overwrite the _first_ buildpack specified. To specify an index, the `--index` flag may be used. This flag is specified starting at a 1-index value, and defaults to `1`.
+
+```shell
+# the following are equivalent commands
+dokku buildpacks:set node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+dokku buildpacks:set --index 1 node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+```
+
+If the index specified is larger than the number of buildpacks currently configured, the buildpack will be appended to the end of the list.
+
+```shell
+dokku buildpacks:set --index 99 node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+```
+
+### Removing a buildpack
+
+> At least one of a buildpack or index must be specified
+
+A single buildpack can be removed by name via the `buildpacks:remove` command.
+
+```shell
+dokku buildpacks:remove node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+```
+
+Buildpacks can also be removed by index via the `--index` flag. This flag is specified starting at a 1-index value.
+
+```shell
+dokku buildpacks:remove node-js-app --index 1
+```
+
+### Clearing all buildpacks
+
+> This does not affect automatically detected buildpacks, nor does it impact any specified `BUILDPACK_URL` environment variable.
+
+The `buildpacks:clear` command can be used to clear all configured buildpacks for a specified app.
+
+```shell
+dokku buildpacks:clear node-js-app
+```
+
+### Displaying buildpack reports for an app
+

-
-In certain cases you may want to specify a custom buildpack. While Dokku uses herokuish to support all the [official heroku buildpacks](https://github.com/gliderlabs/herokuish#buildpacks), it is possible that the buildpack detection does not work well for your application. As well, you may wish to use a custom buildpack to handle specific application logic.

-To use a specific buildpack, you can run the following Dokku command:
-
-```shell
-# replace REPOSITORY_URL with your buildpack's url
-dokku config:set node-js-app BUILDPACK_URL=REPOSITORY_URL
-
-# example: using a specific ruby buildpack version
-dokku config:set node-js-app BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-ruby.git#v142
-```
-
-Please check the documentation for your particular buildpack as you may need to include configuration files (such as a Procfile) in your project root.
-
-## Using multiple buildpacks
-
-You can only set a single buildpack using the `BUILDPACK_URL`, though there may be times when you wish to use multiple buildpacks. To do so, simply create a `.buildpacks` file in the base of your repository. This file should list all the buildpacks, one-per-line. For instance, if you wish to use both the `nodejs` and `ruby` buildpacks, your `.buildpacks` file should contain the following:
-
-```shell
-https://github.com/heroku/heroku-buildpack-nodejs.git#v87
-https://github.com/heroku/heroku-buildpack-ruby.git#v142

+### Using a specific buildpack version
 
 > Always remember to pin your buildpack versions when using the multi-buildpacks method, or you may find deploys changing your deployed environment.
 
-You may also choose to set just a single buildpack in this file, though that is up to you.

-Please check the documentation for your particular buildpack(s) as you may need to include configuration files (such as a Procfile) in your project root.

-## Using a specific buildpack version
-
-As Dokku pins all buildpacks via herokuish releases, there may be occasions where a local buildpack version is out of date. If you wish to use a more recent version of the buildpack, you may use any of the above methods to specify a buildpack **without** the git sha attached like so:
+By default, Dokku uses the [gliderlabs/herokuish](https://github.com/gliderlabs/herokuish/) project, which pins all of it's vendored buildpacks. There may be occasions where the pinned version results in a broken deploy, or does not have a particular feature that is required to build your project. To use a more recent version of a given buildpack, the buildpack may be specified *without* a Git commit SHA like so:
 
 ```shell
 # using the latest nodejs buildpack
-dokku config:set node-js-app BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-nodejs
+dokku buildpacks:set node-js-app https://github.com/heroku/heroku-buildpack-nodejs
 ```
 
-You may also wish to use a **specific** version of a buildpack, which is also simple
+This will use the latest commit on the `master` branch of the specified buildpack. To pin to a newer version of a buildpack, a sha may also be specified by using the form `REPOSITORY_URL#COMMIT_SHA`, where `COMMIT_SHA` is any tree-ish git object - usually a git tag.
 
 ```shell
 # using v87 of the nodejs buildpack
-dokku config:set node-js-app BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-nodejs#v87

+
+# Plugin Building Tips
+
+## Always create a `plugin.toml`
+
+The `plugin.toml` file is used to describe the plugin in help output, and helps users understand the purpose of the plugin. This _must_ have a description and a version. The version _should_ be bumped at every plugin release.
+
+```toml
+[plugin]
+description = "dokku example plugin"
+version = "0.1.0"
+[plugin.config]
+```
+
+## Files should be executable
+
+Commands, subcommands, triggers and source shell scripts should all be executable. On a Unix-like machine, the following command can be used to make them executable:
+
+```shell
+chmod +x path/to/file
+```
+
+Non-executable commands, subcommands, and triggers will be ignored.
+
+## Use the `pipefail` bash option
+
+Consider whether to include the `set -eo pipefail` option. Look at the following example:
+
+```shell
+IMAGE=$(docker images | grep "user/repo" | awk '{print $3}')
+if [[ -z $IMAGE ]]; then
+  dokku_log_fail "user/repo image not found... Did you run 'dokku plugin:install'?"
+fi
+```
+
+If `user/repo` doesn't exist, Dokku exits just before the `awk` command and the `dokku_log_fail` message will never go to `STDOUT`. printed with echo. The `set -e` option should be used in this case.
+
+Here is the `help` entry for `set`:
+
+```
+help set
+Options:
+  -e  Exit immediately if a command exits with a non-zero status.
+  -o option-name
+      pipefail     the return value of a pipeline is the status of
+                   the last command to exit with a non-zero status,
+                   or zero if no command exited with a non-zero status
+```
+
+## Support trace mode
+
+Trace mode is useful for getting debugging output from plugins when the `--trace` flag is specified or `dokku trace:on` is triggered. This should be done at the top of each shell script:
 
 ```shell
 #!/usr/bin/env bash
-set -eo pipefail; [[ $DOKKU_TRACE ]] && set -x
+set -eo pipefail
+[[ $DOKKU_TRACE ]] && set -x
+```
+
+In the above example, the third line enables bash's debug mode, which prints command traces before executing command.
+
+## Verify the existence of dependencies
+
+If a plugin depends on a specific command-line tool, check whether that tool exists before utilizing it. Either `command -v` or `which` may be used to do so:
+
+```shell
+# `command -v` example
+if ! command -v "nginx" &>/dev/null; then
+  log-fail "Missing nginx, install it"
+fi
+
+# `which` example
+if ! which nginx >/dev/null 2>&1; then
+  log-fail "Missing nginx, install it"
+fi
+```
+
+In cases where a dependency should be installed before the plugin can be used at all, use the `dependencies` plugin trigger to install the dependency.
+
+## Implement a help command
+
+For plugins which expose commands, implement a `help` command. This may be empty, but should contain a listing of all available commands.
+
+Commas - `,` - are used in the help output for columnizing output. Verify that the plugin conforms to the spec by running `dokku help --all` and manually verifying the output.
+
+See the sample plugin below for an example.
+
+## Namespace commands
+
+All commands *should* be namespaced. In cases where a core plugin is overriden, the plugin _may_ utilize the a namespace in use by the core, but generally this should be avoided to reduce confusion as to where the command is implemented.
+
+## Implement a proper catch-all command
+
+As of 0.3.3, a catch-all should be implemented that exits with a `DOKKU_NOT_IMPLEMENTED_EXIT` code. This allows Dokku to output a `command not found` message.
+
+See the sample plugin below for an example.
+
+## Set app config without restarting
+
+In the case that a plugin needs to set app configuration settings and a restart should be avoided (default Heroku-style behavior) these "internal" commands provide this functionality:
+
+```shell
+config_set --no-restart node-js-app KEY1=VALUE1 [KEY2=VALUE2 ...]
+config_unset --no-restart node-js-app KEY1 [KEY2 ...]
+```
+
+## Expose functionality in a `functions` file
+
+To allow other plugins access to (some of) a plugin's functionality, functions can expose by including a `functions` file in the plugin for others to source. All functions in that file should be considered publicly accessible by other plugins.
+
+Any functions that must be kept private should reside in the plugin's `trigger/` or `commands/` directories. Other files may also be used to hide private functions; the official convention for hiding private functions is to place them an `internal-functions` file.
+
+## Use helper functions to fetch app images
+
+> New as of 0.4.0
+
+Dokku allows image tagging and deployment of tagged images. This means hard-coding the `$IMAGE` as `dokku/$APP` is no longer sufficient.
+
+Plugins should use `get_running_image_tag()` and `get_app_image_name()` as sourced from `common/functions`. See the [plugin triggers](/docs/development/plugin-triggers.md) doc for examples.
+
+> **Note:** This is only for plugins that are not `pre/post-build-*` plugins
+
+## Use `$DOCKER_BIN` instead of `docker` directly
+
+> New as of 0.17.5
+
+Certain systems may require a wrapper function around the `docker` binary for proper execution. Utilizing the `$DOCKER_BIN` environment variable when calling docker for those functions is preferred.
+
+```shell
+# good
+"$DOCKER_BIN" run -d $IMAGE /bin/bash -e -c "$COMMAND"
+
+# bad
+docker run -d $IMAGE /bin/bash -e -c "$COMMAND"
+```
+
+## Include labels for all temporary containers and images
+
+> New as of 0.5.0
+
+As of 0.5.0, labels are used to help cleanup intermediate containers with `dokku cleanup`. Plugins that create containers and images should add the correct labels to the `build`, `commit`, and `run` docker commands.
+
+Note that where possible, a label `com.dokku.app-name=$APP` - where `$APP` is the name of the app - should also be included. This enables `dokku cleanup APP` to cleanup the specific containers for a given app.
+
+```shell
+# `docker build` example
+"$DOCKER_BIN" build "--label=com.dokku.app-name=${APP}" $DOKKU_GLOBAL_BUILD_ARGS ...
+
+# `docker commit` example
+# Note that the arguments must be set as a local array
+# as arrays cannot be exported in shell
+local DOKKU_COMMIT_ARGS=("--change" "LABEL org.label-schema.schema-version=1.0" "--change" "LABEL org.label-schema.vendor=dokku" "--change" "LABEL $DOKKU_CONTAINER_LABEL=")
+"$DOCKER_BIN" commit --change "LABEL com.dokku.app-name=$APP" "${DOKKU_COMMIT_ARGS[@]}" ...
+
+# `docker run` example
+"$DOCKER_BIN" run "--label=com.dokku.app-name=${APP}" $DOKKU_GLOBAL_RUN_ARGS ...
+```
+
+## Copy files from the built image using `copy_from_image`
+
+Avoid copying files from running containers as these files may change over time. Instead copy files from the image built during the deploy process. This can be done via the `copy_from_image` helper function. This will correctly handle various corner cases in copying files from an image.
+
+```shell
+source "$PLUGIN_CORE_AVAILABLE_PATH/common/functions"
+
+local TMP_FILE=$(mktemp "/tmp/dokku-${DOKKU_PID}-${FUNCNAME[0]}.XXXXXX")
+trap "rm -rf '$TMP_FILE' >/dev/null" RETURN INT TERM
+
+local IMAGE_TAG="$(get_running_image_tag "$APP")"
+local IMAGE=$(get_deploying_app_image_name "$APP" "$IMAGE_TAG")
+copy_from_image "$IMAGE" "file-being-copied" "$TMP_FILE" 2>/dev/null
+```
+
+Files are copied from the `/app` directory - for images built via buildpacks - or `WORKDIR` - for images built via Dockerfile.
+
+## Avoid calling the `dokku` binary directly
+
+> New as of 0.6.0
+
+Plugins should **not** call the `dokku` binary directly from within plugins because clients using the `--app` argument are potentially broken when doing so.
+
+Plugins should instead source the `functions` file for a given plugin when attempting to call Dokku internal functions.

-A few notes:
-
-- Don't forget to `chmod +x` your executable files.
-- You should always support `DOKKU_TRACE` as specified on the 2nd line of the plugin.
-- If your command requires that an application exists, ensure you check for it's existence in the manner prescribed above.
-- A `help` command is required, though it is allowed to be empty. Also, the command syntax will need to separated by `, ` in order to maintain columnar output alignment.
-- Commands *should* be namespaced.
-- As of 0.3.3, a catch-all should be implemented which exits with a `DOKKU_NOT_IMPLEMENTED_EXIT` code. This allows Dokku to output a `command not found` message.
-- Be sure you want the "set -eo pipefail" option. Look at the following example :
-
-    ```shell
-    IMAGE=$(docker images | grep "user/repo" | awk '{print $3}')
-    if [[ -z $IMAGE ]]; then
-        dokku_log_fail "user/repo image not found... Did you run 'dokku plugin:install'?"
-    fi
-    ```
-
-  In the case where the "user/repo" is not installed, Dokku exits just before the awk command,
-  you will never see the message printed with echo. You just want "set -e" in this case.
-
-  Here is the documentation of the 'set -eo pipefail' option:
-  ```
-  help set
-    Options:
-      -e  Exit immediately if a command exits with a non-zero status.
-      -o option-name
-          pipefail     the return value of a pipeline is the status of
-                       the last command to exit with a non-zero status,
-                       or zero if no command exited with a non-zero status
-  ```
-- As some plugins require access to set app config settings and do not want/require the default Heroku-style behavior of a restart, we have the following "internal" commands that provide this functionality :
-
-  ```shell
-  dokku config:set --no-restart node-js-app KEY1=VALUE1 [KEY2=VALUE2 ...]
-  dokku config:unset --no-restart node-js-app KEY1 [KEY2 ...]
-  ```
-- From time to time you may want to allow other plugins access to (some of) your plugin's functionality. You can expose this by including a `functions` file in your plugin for others to source. Consider all functions in that file to be publicly accessible by other plugins. Any functions not wished to be made "public" should reside within your plugin trigger or commands files.
-- As of 0.4.0, we allow image tagging and deployment of said tagged images. Therefore, hard-coding of `$IMAGE` as `dokku/$APP` is no longer sufficient.

+```
+
+## Trace Mode
+
+By default, Dokku will constrain the amount of output displayed for any given command run. The verbosity of output can be increased by enabling trace mode. Trace mode will turn on the `set -x` flag for bash plugins, while other plugins are free to respect the environment variable `DOKKU_TRACE` and log differently as approprate. Trace mode can be useful to see _where_ plugins are running commands that would otherwise be unexpected.
+
+To enable trace mode, run `trace:on`
+
+```shell
+dokku trace:on
+```
+
+```
+-----> Enabling trace mode

 In Dokku 0.5.0, port proxying was decoupled from the `nginx-vhosts` plugin into the proxy plugin. Dokku 0.6.0 introduced the ability to map host ports to specific container ports. In the future this will allow other proxy software - such as HAProxy or Caddy - to be used in place of nginx.
 
 ## Usage
 
+> Warning: Mapping alternative ports may conflict with the active firewall installed on your server or hosting provider. Such software includes - but is not limited to - AWS Security Groups, iptables, and UFW. Please consult the documentation for those softwares as applicable.

 From Dokku versions `0.5.0` until `0.11.0`, enabling or disabling an application's proxy would **also** control whether or not the application was bound to all interfaces - e.g. `0.0.0.0`. As of `0.11.0`, this is now controlled by the network plugin. Please see the [network documentation](/docs/networking/network.md#container-network-interface-binding) for more information.
