How to upgrade docker containers

Solution:

1. Upgrade Image

Just pull the latest data from the server.

docker pull quay.io/sameersbn/redmine:latest

2. Close the old container and delete

to the working directory/data, use docker-compose to close the first-level container

cd /data
docker-compose stop
docker rm data_redmine_1

3. Restart the new container

Due to the code upgrade, some new environment parameter configurations have been added

REDMINE_SECRET_TOKEN
DB_NAME

One of these two was prompted by the log, and the other found that after the service upgrade, the old user could not log in. I checked the reason. I found out that it was because the default value of the database name had changed. There are many other parameters that may be affected, so you need to take a closer look at the details page.

docker-compose start

4. Upgrade the database

docker exec -it data_redmine_1 bash
cd $WORKDIR
RAILS_ENV=production bundle exec rake db:migrate
