Notes on upgrading Docker containers

No particular notes, the plan is to remove this entirely at some point.

-----
|
|
|
|
This is a little tricky, because you want to dump the database from the current
|
|
container, upgrade the container, and then restore the database. Something
|
|
like the following will work:
|
|
|
|
# dump the db
|
|
MYSQL_CONTAINER=gaz_mysql_1
|
|
PASSWORD=$(grep MYSQL_ROOT_PASSWORD docker-compose.yml|cut -d= -f2)
|
|
docker exec $MYSQL_CONTAINER sh -c "exec mysqldump --all-databases -uroot -p'$PASSWORD'" > all-databases.sql
|
|
|
|
# do the upgrade
|
|
docker compose up -d
|
|
|
|
# restore the dump
|
|
docker exec -i $MYSQL_CONTAINER sh -c "exec mysql -uroot -p'$PASSWORD'" < all-databases.sql
|
|
|
|
# run the mysql upgrade when moving across major versions
|
|
docker exec -it $MYSQL_CONTAINER mysql_upgrade -u root -p$PASSWORD
|
|
|
|
# Some custom functions may need to be recreated (the site will error on load)
|
|
git grep -l 'CREATE FUNCTION' misc/my-migrations
|
|
misc/my-migrations/20180104060449_tables.php
|
|
misc/my-migrations/20200320183228_bonus_accrual_function.php
|
|
|
|
Execute the function definition statements in the mysql client.

--------

|
|
|
Just upgrade to the latest image (see Dockerhub)
