How to update your Docker containers
From time to time you may have a need to update the containers themselves. Primarily this is done for security releases.
1. Update docker-compose.yml
The first thing you need to do is to edit your docker-compose.yml file and replace the version of the container with the new one you wish to use.
Navigate to your docker-compose.yml file and open it to edit. On Debian installs it would look like this:
cd /usr/local/archipelago/deploy/archipelago-deployment-live/deploy/ec2-docker
vi docker-compose.yml
You want to change the image line to reflect the name of the new image you wish to use:
image: esmero/php-7.4-fpm:1.0.0-RC3-multiarch
might become:
image: esmero/php-8.0-fpm:1.1.0-multiarch
Save your change. If use vi like in the above it would look like this:
:wq
Pull the new image(s)
Docker Compose will now allow us to grab the new image(s) while your current system is running:
docker-compose pull
Stop and restart the container
It is necesary to stop and start the container or the current image will continue to be used:
docker-compose stop container-name
Wait for it to stop. Then bring it back up:
docker-compose up -d
It is important to use the -d flag or you will have your live instance stuck in your terminal. You want it to run in the background. The -d flag stands for detached.
Down and up
If you are more comfortable having the all the containers go down and up you can do that with the following:
docker-compose down
docker-compose up
