Docker Build Stuck on MariaDB Installation - docker

Question

I am trying to build a set of Docker images that includes an installation of Magento 2 and MariaDB. In rare cases it succeeds (although this could be due to small changes in the app), but in most cases it is stuck on the following:
magento2-db | Version: '10.3.11-MariaDB-1:10.3.11+maria~bionic' socket: '/var/run/mysqld/mysqld.sock' port: 3306 mariadb.org binary distribution
I see that someone else had this issue, but the cause was actual RUN commands for MariaDB installation, which I don't directly call. There doesn't seem to be anything in the log to indicate an error either.
The last lines in the log are:
[16:49:18.424][Moby ][Info ] [25693.252573] br-83922f7da47b: port 2(vethac51834) entered blocking state

It seems to actually finish executing all steps in the Dockerfile, but I suspect there might be a problem in my docker-compose file, which looks like this:
version: '3.0'
services:
app:
build:
context: .
dockerfile: .docker/Dockerfile
container_name: 'magento-2.2.6'
ports:
- "80:80"
volumes:
- magento2-test-env:/var/www/html/magento2 # will be mounted on /var/www/html
links:
- magento2-db
env_file:
- .docker/env
depends_on:
- magento2-db
magento2-db:
container_name: 'magento2-db'
image: mariadb:latest
ports:
- "9809:3306"
volumes:
- magento2-db-data:/var/lib/mysql/data
env_file:
- .docker/env
volumes:
magento2-db-data:
magento2-test-env:
external: true
Is there anything obviously wrong with my setup, and is there a good way to troubleshoot this, maybe look for something specific in the log?

Answer 1

maybe the way you're building your composer what's the problem.
Try use this one:
version: '3.0'
services:
app:
build:
context: .
dockerfile: .docker/Dockerfile
container_name: 'magento-2.2.6'
ports:
- "80:80"
volumes:
- magento2-test-env:/var/www/html/magento2 # will be mounted on /var/www/html
links:
- magento2-db
env_file:
- .docker/env
depends_on:
- db
db:
container_name: 'magento2-db'
image: mariadb:latest
ports:
- "9809:3306"
volumes:
- /var/lib/mysql/data
env_file:
- .docker/env
volumes:
magento2-db-data:
magento2-test-env:
external: true
Avoid to use services names like 'blabla-something' if you need put a name use as container_name it'll be enough, and the db, links always should links in the services itself no in the containers name.
I hope this could help you.

Answer 2

Try setting -e MYSQL_INITDB_SKIP_TZINFO=1, refer to this issue.
e.g.
docker run -it --rm -e MYSQL_INITDB_SKIP_TZINFO=1 ... mariadb:10.4.8
