![]() ![]() So I'd like to find out why this damn mysqld is listening on port 0 the first time I launch the container after building. ![]() The thing is that due to the crash, the end of the initialization was not executed, including my scripts and the databases creation along with users. The problem was not pretty visible because when launching the container a second time, the initialization was skipped, the good port was configured, and the server worked fine. The container tries to connect to MySQL and crash due to the port. I already tried a proposed solution to configure manually the port in custom.cnf but it does not work. The main clue in the logs is that line : Version: '5.7.15' socket: '/var/run/mysqld/mysqld.sock' port: 0 MySQL Community Server (GPL) Now the container runs a few seconds after building, then crash. This chmod command is meant to avoid this kind of error #!bin/bashĪll this stuff is working, except that I haven't any root access, blocking me from creating databases or mysql users for my apps !Ä®DIT: After days of investigation, and an issue in docker-library/mysql repository, we found out that one of the problems was a deprecated configuratio key in custom.cnf.

The dos2unix command is meant to convert Windows line endings to Unix. Only MYSQL_ROOT_PASSWORD deserves interest (perhaps this statement is the cause of my failure to make this work.! ). So I am not sure why it is not generating sometime and generate sometime. Most of the environment variables are used in scripts and applications independantly from the MySQL server. shrenikp7 January 7, 2020, 7:16pm 1 I have created docker container on Overlay Network, and when I execute docker logs I donât find MySQL user - root password generated.In this matter I've encountered quite a problem : my MySQL container, extending the MySQL official Docker image, seems to fail to create the root account, despite the setting of the MYSQL_ROOT_PASSWORD environment variable in my docker-compose`.yml. To delete the container, make sure that it is stopped.Today I'm trying to make my Docker environment working ! To stop the container, simply execute the next command: docker stop mysql1 After inserting the password, you should be inside MySQL This will require the root password set in the previous step. To connect, we will first run the next command: docker exec -it mysql1 mysql -uroot -p 3.Connecting to MySQL Server from within the container After the container is initializedĪnd ready to run, you will se it change to (healthy). In the status column of the result from above, you can see the (health: starting) mention. This will list all the running containers as shown above. To verify if the container was created and running, we can execute a docker ps (process status) command: docker psĬONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESħ9742fe73ea9 mysql/mysql-server:8.0 "/entrypoint.sh mysqâ¦" 24 hours ago Up 6 seconds (health: starting) 3306/tcp, 33060/tcp mysql1 environment: MYSQLDATABASE: mysqldb2 MYSQLROOTPASSWORD: Welcome123. mysql/mysql-server:8.0 - will specify what image to run in the newly created container 1 Answer Sorted by: 4 You can escape the if with a double. ![]() Here you can insert whatever password you want
