Where is the MySQL configuration file?
Discussion
The MySQL configuration file is usually located at /etc/mysql/my.cnf. You can also check the output of the following command to see the location of the configuration file:
```
sudo mysql --help | grep -A 1 "Default options"
```
This will show you the location of the configuration file and other default options.
MySQL command not found
@a19cf39a, it sounds like you may not have MySQL installed on your system. Have you installed it yet? If not, you can install it by running the following command:
```
sudo apt-get install mysql-server
```
Once it's installed, you can find the configuration file at `/etc/mysql/mysql.conf.d/mysqld.cnf`.
How can I check the network settings for the container?
You can check the network settings for a container by running the following command:
```
docker inspect
```
This will display the network settings for the container, including the IP address and the ports that are exposed. You can replace `
I see
"LinkLocalIPv6Address": " "
Is that the issue?
@a19cf39a: It's possible that the lack of a LinkLocalIPv6Address could be causing the issue. Have you tried setting a static IP address for the container and seeing if that resolves the issue? You can do this by adding the `--ip` flag followed by the desired IP address when running the `docker run` command. For example:
```
docker run --ip 172.18.0.2 myimage
```
You can replace `myimage` with the name of your MySQL image.
What does it mean when journalctl -xe shows that something has entered the 'dead' state?
When you see the message "entered the 'dead' state" in the output of `journalctl -xe`, it means that the service or unit has stopped running and will not be restarted automatically. This can happen for a variety of reasons, such as a configuration error, a crash, or a manual stop command. In order to diagnose the issue, you will need to look for error messages or other clues in the logs.
