# Plugin Config Version 1 of Plugin V2
|
||||
|
||||
This document outlines the format of the V0 plugin configuration. The plugin
|
||||
config described herein was introduced in the Docker daemon in the [v1.12.0
|
||||
release](https://github.com/docker/docker/commit/f37117045c5398fd3dca8016ea8ca0cb47e7312b).

This document outlines the format of the V0 plugin configuration.

Plugin configs describe the various constituents of a docker plugin. Plugin
|

configs can be serialized to JSON format with the following media types:

|

First, start a container.
|
||||
|
||||
```console
|
||||
$ docker run --name ubuntu_bash --rm -i -t ubuntu bash
|
||||
$ docker run --name mycontainer -d -i -t alpine /bin/sh
|
||||
```
|
||||
|
||||
This will create a container named `ubuntu_bash` and start a Bash session.
|
||||
This creates and starts a container named `mycontainer` from an `alpine` image
|
||||
with an `sh` shell as its main process. The `-d` option (shorthand for `--detach`)
|
||||
sets the container to run in the background, in detached mode, with a pseudo-TTY
|
||||
attached (`-t`). The `-i` option is set to keep `STDIN` attached (`-i`), which
|
||||
prevents the `sh` process from exiting immediately.
|
||||
|
||||
Next, execute a command on the container.
|
||||
|
||||
```console
|
||||
$ docker exec -d ubuntu_bash touch /tmp/execWorks
|
||||
$ docker exec -d mycontainer touch /tmp/execWorks

Next, execute an interactive `sh` shell on the container.

```console

$ docker exec -it ubuntu_bash bash

$ docker exec -it mycontainer sh
|
||||
```
|
||||
|

This will create a new Bash session in the container `ubuntu_bash`.
|
||||
This starts a new shell session in the container `mycontainer`.
|
||||
|
||||
### <a name="env"></a> Set environment variables for the exec process (--env, -e)
|
||||
|
||||
Next, set environment variables in the current bash session.
|
||||
|
||||
By default, the `docker exec` command, inherits the environment variables that
|
||||
are set at the time the container is created. Use the `--env` (or the `-e` shorthand)
|
||||
to override global environment variables, or to set additional environment variables
|
||||
for the process started by `docker exec`.
|
||||
|
||||
The example below creates a new shell session in the container `mycontainer` with
|
||||
environment variables `$VAR_A` and `$VAR_B` set to "1" and "2" respectively.
|
||||
These environment variables are only valid for the `sh` process started by that
|
||||
`docker exec` command, and are not available to other processes running inside
|
||||
the container.
|
||||
|
||||
```console
|
||||
$ docker exec -it -e VAR_A=1 -e VAR_B=2 ubuntu_bash bash
|
||||
$ docker exec -e VAR_A=1 -e VAR_B=2 mycontainer env
|
||||
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
|
||||
HOSTNAME=f64a4851eb71
|
||||
VAR_A=1
|
||||
VAR_B=2
|
||||
HOME=/root
|
||||
```
|
||||
|
||||
This will create a new Bash session in the container `ubuntu_bash` with environment
|
||||
variables `$VAR_A` and `$VAR_B` set to "1" and "2" respectively. Note that these
|
||||
environment variables will only be valid on the current Bash session.
|
||||
### <a name="workdir"></a> Set the working directory for the exec process (--workdir, -w)

||||

You can specify an alternative working directory for the command to execute

### Pull an image from Docker Hub

|

To download a particular image, or set of images (i.e., a repository), use
|

`docker pull`. If no tag is provided, Docker Engine uses the `:latest` tag as a

||||
default. This command pulls the `debian:latest` image:

||||
`docker image pull` (or the `docker pull` shorthand). If no tag is provided,
