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 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 command or docker ps.
# 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:

  • mariadb
  • php
  • varnish
  • nginx
  • ssl-terminator
  • redis
  • elasticsearch

Usage example

yarn run exec mariadb
>root@c8f223c3ea92:/# # inside a container with mariadb database
# ctrl + d or type 'exit' and press enter
# this is not alias, but rather service name matching
yarn run exec ma
>root@c8f223c3ea92:/# # inside a container with mariadb database
# custom command to check for nginx service status in container
yarn run exec nginx service nginx status
# expected output
>[ ok ] nginx is running.
