Docker

Shell onto a docker container

On an Alpine Linux OS docker image, use sh shell (or ash - TBC)

docker exec -it container-name /bin/sh

On a debian / ubuntu based docker image use bash shell

docker exec -it container-name /bin/bash

Run mysql database image

docker run --rm -p 127.0.0.1:3306:3306  --name mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -e MYSQL_DATABASE=dbname -e MYSQL_USER=dev -e MYSQL_PASSWORD=$DB_PASSWORD mysql:5.7

Run clojure tests in docker container that uses the alpine image (not for a multi-stage dockerfile as it would required code and tests to be in the run-time image)

docker run clojure-service-container sh -c "clojure -X:env/test:test/run"

The sh -c let you run any command inside your container, over-riding a CMD or entrypoint directive in the Dockerfile
