A few tiny, useful Docker scripts, to be placed in one's `$PATH` and made executable

docker-bash

#!/bin/bash

# Shell into the Docker container with the given name.
# eg: `docker-bash my_app`
# Note: fails if more than one id is returned.
ID=$(docker-id $1)
docker exec -it $ID bash

docker-id

#!/bin/bash

# Output the id(s) of running Docker containers with the given name.
# eg: `docker-id my_app`
docker ps |grep $1 |cut -d' ' -f 1

docker-sh

#!/bin/bash

# Shell into the Docker container with the given name.
# eg: `docker-sh my_app`
# Note: fails if more than one id is returned.
ID=$(docker-id $1)
docker exec -it $ID sh
