A handy alias to execute a command inside a docker container with a specific name (interactive mode)

docker exec alias

# put this in ~/.bashrc, or ~/.zshrc, etc., then source ~/.bashrc or source ~/.zshrc
# Use it like dexec <containername> <command> : dexec node bash
 dexec() {
  name=${1}
  command=${2}
  docker exec -ti $(docker ps | grep $name | awk '{print $1}') $command
}
