Docker attach to running container

Attach to the running Docker container interactively using FZF.

Install FZF: brew install fzf

Add the following function to the .bashrc or .zshrc

1dex() {
2    CONTAINER=$(docker ps | grep -v CONTAINER | awk '-F ' ' {print $NF}' | fzf)
3    if [ ! -z "$CONTAINER" ]
4    then
5        docker exec -it "$CONTAINER" bash
6    fi
7}

Let's break it down:

1. docker ps Lists all running Docker containers
2. grep -v CONTAINER Filter out headers from docker ps output
3. awk '-F ' ' {print $NF}' Extracts only container names
4. fzf Select a container using FZF
5. if [ ! -z "$CONTAINER" ] Checking if container was selected
6. docker exec -it "$CONTAINER" bash - opens an interactive shell in the selected container.
