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
# clean db
$ docker compose exec backend yarn db:reset
# seed db
$ docker compose exec backend yarn db:seed

# for production
$ docker compose -f docker-compose.yml -f docker-compose.apple-m1.override.yml up
# init admin user
$ docker compose exec backend /bin/sh -c "yarn prod:migrate init"

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 "ocelotsocialnetwork/<app-name>:local-<layer-name>" --build-arg BBUILD_DATE="<build-date>" --build-arg BBUILD_VERSION="<build-version>" --build-arg BBUILD_COMMIT="<build-commit>" <app-folder-name-or-dot>/

The build arguments are optional.

For the specific applications, we use them as follows.

Backend

Production For Backend

# in main folder
$ dive build --target production -t "ocelotsocialnetwork/backend:local-production" backend/

Development For Backend

# in main folder
$ dive build --target development -t "ocelotsocialnetwork/backend:local-development" backend/

Webapp

Production For Webapp

# in main folder
$ dive build --target production -t "ocelotsocialnetwork/webapp:local-production" webapp/

Development For Webapp

# in main folder
$ dive build --target development -t "ocelotsocialnetwork/webapp:local-development" webapp/
