Docker hangs after running multiple MySQL image with volume data directory more than once

(Giuseppe Maxia) #1

Expected behavior

The containers are responsive.

Actual behavior

Docker hangs! It does not respond to any command.

Steps to reproduce the behavior

(1) Run three MySQL containers, using scripts listed in mysql-replication-samples/docker-replication.
The image used is mysql/mysql-server.

Run this command to start three MySQL containers, using a volume for data directory
The files are created under $HOME/docker/mysql


(2) Then, remove the containers


(3) Repeat the above commands a few times. Depending on the amount of RAM assigned to Docker, operations may succeed a few times before failing.

Running the same operations without volumes ( export SKIP_VOLUME=1) will run many times without failures.
