Please bear with me. Pretty new to Docker.
I'm deploying Docker containers (detached) to an AWS EC2 registry using CodeDeploy. On deploy, the following command is run after setting some environmental variables etc:
exec docker run -d ${PORTS} -v cache-${CACHE_VOLUME} --env-file $(dirname $0)/docker.env --tty "${IMAGE}:${TAG}"
The container runs an image located and tagged in EC2 Container Service. No problems so far.
Since this is a PHP application (specifically a Symfony2 application) I would normally need to issue the following command to execute database migrations on deployment:
php app/console doctrine:migrations:migrate --no-interaction
Now, is there any to run this command during "docker run..." while keeping the container running, or do I need to run another container specifically for this command?
Many thanks!
AWS and Docker have collaborated to make a simplified developer experience that enables you to deploy and manage containers on Amazon ECS directly using Docker tools. You can now build and test your containers locally using Docker Desktop and Docker Compose, and then deploy them to Amazon ECS on Fargate.
AWS services such as AWS Fargate, Amazon ECS, Amazon EKS, and AWS Batch make it easy to run and manage Docker containers at scale.
Just leaving this here for the next one that searches for this... ;-)
When using a recent version of Doctrine, there is a pretty handy parameter for this:
php bin/console doctrine:migrations:migrate --no-interaction --allow-no-migration
The "allow-no-migration" parameter instructs doctrine not to throw an exception, when there is nothing to do...
You need create entrypoint. This script runs at the container startup.
entrypoint.sh file:
#create or update db
./waitforit.sh <DB_HOST>:<DP_PORT> -t 30
php app/console doctrine:migrations:execute
# start apache
apache2-foreground
wait for it it is a script waited when database is started up
I do as follows:
docker-compose exec [containerID] ./app/console migrations:migrate --no-interaction
