Docker More Closely

Apple M1 Platform

Attention: For using Docker commands in Apple M1 environments!

Enviroment Variable For Apple M1 Platform

To set the Docker platform environment variable in your terminal tab, run:

# set env variable for your shell
$ export DOCKER_DEFAULT_PLATFORM=linux/amd64

Docker Compose Override File For Apple M1 Platform

For Docker compose up or build commands, you can use our Apple M1 override file that specifies the M1 platform:

# in main folder

# for development
$ docker compose -f docker-compose.yml -f docker-compose.override.yml -f docker-compose.apple-m1.override.yml up

# for production
$ docker compose -f docker-compose.yml -f docker-compose.apple-m1.override.yml up

Analysing Docker Builds

To analyze a Docker build, there is a wonderful tool called dive. Please sponsor if you're using it!

The dive build command is exactly the right one to fulfill what we are looking for. We can use it just like the docker build command and get an analysis afterwards.

So, in our main folder, we use it in the following way:

# in main folder
$ dive build --target <layer-name> -t "gradido/<app-name>:local-<layer-name>" <app-folder-name-or-dot>/

For the specific applications, see our publish.yml.
