![]() if you have MYSQL_ROOT_PASSWORD then you know the password now.So we know why the password is not in the logs. Would you mind having a look on how you started it with :ĭocker inspect -format '' The later one is probably the one you’re used to use since it’s the only one that print the password in the logs. ![]() 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.To start mysql docker image, you have to set one of these : ![]() 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. This is practically what everyone does without noticing that your PHP application actually exposes MariaDB root password for everyone to see with the variable. 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. Viewed 38k times 5 Today I'm trying to make my Docker environment working 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 MYSQLROOTPASSWORD environment variable in my docker-compose.yml. 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. Set Spring Boot Docker Compose Environment variables. Write Docker Compose configurations in YAML file. 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 !ĮDIT: 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. 45 You could change it from a running container, using a docker exec session, as described in 'Connecting to MySQL Server from within the Container' Once the server is ready, you can run the mysql client within the MySQL Server container you just started and connect it to the MySQL Server. We’re gonna following these steps: Create Spring Boot App working with MySQL database. RUN chmod a+x /my-entrypoint.sh & chown root:root /my-entrypoint.shĮNTRYPOINT version: '3. RUN chmod a+x /docker-entrypoint-initdb.d/databases.sh & chown root:root /docker-entrypoint-initdb.d/databases.sh Then, check to see if the MySQL container is running: docker ps. ![]() version: '3.3' services: database: containername: mysql-dev2 image: mysql:8.0 volumes: - './data/mysql-dev2:/var/lib/mysql-dev2-docker. I tried with the other special character '' and it is starting up. The same for the files you place in /docker-entrypoint-initdb.d. Not able to start mysql container using docker-compose.yaml file, when I use '' sign for the MYSQLROOTPASSWORD. Did you use data-volume already with other settings The password in the environment variable is only used the first time when MySQL is initialized on an empty volume. Here's how to run MySQL while satisfying these prerequisites: docker run -name my-mysql -e MYSQLROOTPASSWORDsecret -v HOME/mysql-data:/ var /lib/mysql -d mysql: 8. Starting the container: PS C:\Sql Server\MySql> docker-compose up This is not the first time you start this database. MySQL will refuse to initialize if this variable isn't set. In this example, we create a container named mysqldocker with the latest version tag: sudo docker run -name containername -d mysql/mysql-server:latest. Use the MYSQLROOTPASSWORD environment variable. ![]() RUN dos2unix /docker-entrypoint-initdb.d/databases.sh & dos2unix /my-entrypoint.sh & dos2unix /etc/mysql/conf.d/custom.cnf & apt-get -purge remove -y dos2unix & rm -rf /var/lib/apt/lists/* Replace imagetagname with the name of the image downloaded in Step 1. When you start the MySQL Docker container, you can pass configuration options to the server through the docker run command. RUN apt-get update & apt-get install -y dos2unixĬOPY conf.d/custom.cnf /etc/mysql/conf.d/ĬOPY docker-entrypoint-initdb.d/databases.sh /docker-entrypoint-initdb.d/databases.sh The custom entrypoint is named differently to avoid overidding the default mysql entrypoint script. 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.! ). Most of the environment variables are used in scripts and applications independantly from the MySQL server. 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. Today I'm trying to make my Docker environment working ! ![]()
