I am not able to start percona mysql dockerized instance if I try to mount the data directory like this:
docker run --name percona57f -p 3384:3306 -v /my/custom3384:/etc/mysql/conf.d -v /storage/data3384:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=india3384 -e INIT_TOKUDB=1 -d percona/percona-server:5.7
The error is as shown below:
[ERROR] --initialize specified but the data directory exists and is not writable. Aborting.
[ERROR] Aborting
The command will work if I do not include the data directory like this...
docker run --name percona57g -p 3384:3306 -v /my/custom3384:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=india3384 -e INIT_TOKUDB=1 -d percona/percona-server:5.7
But it is very important for me to mount the data directory on host machine. Any way to enable this -v /storage/data3384:/var/lib/mysql
Run this command before docker run:
chown 1001 /my/custom3384
This is the UID for the mysql user, as shown in the Dockerfile for the percona image:
https://github.com/percona/percona-docker/blob/master/percona-server/Dockerfile
RUN useradd -u 1001 -r -g 0 -s /sbin/nologin \
-c "Default Application User" mysql
