Removing Images

Constantly creating images can start to add up in storage consumption. Periodically you may wish to either remove just the data not associated with a container or you can remove all data.

# WARNING! This will remove:
#  - all stopped containers
#  - all networks not used by at least one container
#  - all dangling images
#  - all dangling build cache
docker system prune

# WARNING! This will remove:
#  - all stopped containers
#  - all networks not used by at least one container
#  - all images without at least one container associated to them
#  - all build cache
docker system prune -a

Debugging nginx configuration

Build the nginx image if it's not already configured from previous docker-compose builds.

docker build -f nginx/dev.Dockerfile nginx/.

Create a container running the nginx image.

docker run -it xxxxxxxxxxxx /bin/bash

Run test on your nginx configuration.

root@xxxxxxxxxxxx:/# nginx -t
