Review using docker compose

[bjarneo]

Move from plain docker to use docker compose. Easier to handle config & replicas.

Snippet from our makefile (deploys a Symfony application):

SSH_TESTING := some_remote_host
SSH_PRODUCTION := some_remote_host

PHONY += --deploy
--deploy: export COMPOSE_FILE := compose.live.yaml
--deploy: export DOCKER_HOST := ssh://$(SSH)
--deploy:
	$(eval BUILD := $(shell ssh $(SSH) "docker inspect -f '{{ index .Config.Labels \"gha.build\" }}' $(PROJECT)-$(INSTANCE)"))
	BUILD=$(BUILD) op run --env-file="./.env.$(INSTANCE)" -- docker compose config
	BUILD=$(BUILD) op run --env-file="./.env.$(INSTANCE)" -- docker compose up --wait --remove-orphans
	BUILD=$(BUILD) op run --env-file="./.env.$(INSTANCE)" -- docker compose exec app bin/console --ansi cache:clear
	BUILD=$(BUILD) op run --env-file="./.env.$(INSTANCE)" -- docker compose exec app bin/console --ansi about

PHONY += deploy-testing
deploy-testing: INSTANCE := test
deploy-testing: SSH := $(SSH_TESTING)
deploy-testing: --deploy ## Deploy to Testing

PHONY += deploy-production
deploy-production: INSTANCE := prod
deploy-production: SSH := $(SSH_PRODUCTION)
deploy-production: --deploy ## Deploy to Production

So here you can run this like:

Deploy a certain (new) build (we use it within docker image tag):

make deploy-testing BUILD=123

Or re-reploy current build (it gets currently running build number from running container):

make deploy-testing
