Production is deployed via docker-compose file (not much config). It is using blue/green deploys for zero downtime.
So basic work done by deploy.sh is to check if there is new docker imaga available. If there is no new image available, just sleep for next minute. If it is available, start new container using different project name
This part check which deployment is currently running (green or blue)
if [ $(docker ps -f name=prod_blue -q) ]
then
NEW="green"
OLD="blue"
else
NEW="blue"
OLD="green"
fi
Then start container that was not running with new image
echo "Starting "$NEW" container"
docker-compose --project-name=${DEPLOY_ENV}_${NEW} up -d
Wait for some time
Then stop old deploy
echo "Stopping "$OLD" container"
docker-compose --project-name=${DEPLOY_ENV}_$OLD stop
Preview deploy is done by python script, that checks GH for open PR. If PR is open and has deploy-preview label, then script tries to pull corresponding docker image )(having tag pr-###). If image exists, then container is run with some flags and labels (remove=True, so it is removed when stopped, also routing labels for tarefik are set).
At same time, for every running preview container, corresponsing PR on GH is checked if it is still open and having deploy-preview label. If not, container is stopped.
