# Execute commands in Docker containers

## `yarn run exec <container name> [commands]` or `npm run exec -- <container name> [commands]`

Executes command in a chosen container.

This command is basically a wrapper on top of [docker exec](https://docs.docker.com/engine/reference/commandline/exec/) command. It simplifies execution command in docker containers by providing names for docker containers so you don't have to search them by running a [status](https://docs.create-magento-app.com/v1/getting-started/available-commands/status) command or `docker ps`.

```bash
# Using docker exec

# 1. get container name
docker ps
> ... # docker ps otput

# 2. execute command
docker exec -it <container name> <command>

# Using CMA exec

# 1. execute command
yarn run exec <service name> <command>
> ... # output from command is piped to your terminal
```

If you don't want to execute specific command, by default exec command will use **bash** as a command (and **redis-cli** for redis container) so you will be connected to the container with interactive shell environment.

### **Available container names**:

* `mysql`
* `nginx`
* `redis`
* `elasticsearch`

## Usage example

```bash
yarn run exec mysql

>root@c8f223c3ea92:/# # inside a container with mysql database

# ctrl + d or type 'exit' and press enter

# this is not alias, but rather service name matching
yarn run exec m

>root@c8f223c3ea92:/# # inside a container with mysql database

# custom command to check for nginx service status in container
yarn run exec nginx service nginx status

# expected output
>[ ok ] nginx is running.
```
