If your system is running a software firewall (or behind a hardware firewall or NAT) you must allow connections destined to TCP port that MariaDB runs on (by default and almost always 3306).
Why is MariaDB bound to loopback?
MariaDB is bound to the loopback interface by default because it makes it impossible to connect to the TCP port on the server from a remote host (the bind-address must refer to a local IP address, or you will receive a fatal error and MariaDB will not start). This of course is not desirable if you want to use the TCP port from a remote host, ...
What is MariaDB bind address?
Some MariaDB packages bind MariaDB to 127.0.0.1 (the loopback IP address) by default as a security measure using the bind-address configuration directive. Old MySQL packages sometimes disabled TCP/IP networking altogether using the skip-networking directive. Before going in to how to configure these, let's explain what each of them actually does:
Why doesn't MariaDB work on localhost?
However, this doesn't work when MariaDB is running inside a container because the server's filesystem is isolated from the host.
What is Docker container?
In many cases, the best solution is using containers. Docker is a framework that runs containers. A container is meant to run a specific daemon, and the software that is needed for that daemon to properly work.
What is Docker package?
Docker is an open source project, released under the Apache License, version 2. Note that, while your package repositories could have a package called docker, it is probably not the Docker we are talking about. The Docker package could be called docker.io or docker-engine.
Does Docker virtualize a whole system?
Docker does not virtualize a whole system; a container only includes the packages that are not included in the underlying system. Docker requires a very small amount of resources. It can run on a virtualized system. It is used both in development and in production environments.
Can you download an image from Docker?
Once you have found an image that you want to use, you can download it via Docker. Some layers including necessary dependencies will be downloaded too. Note that, once a layer is downloaded for a certain image, Docker will not need to download it again for another image.
Can MariaDB connect to TCP?
The client can't access the socket file which is inside the container, so it fails to connect. Therefore connections to the MariaDB server must be made using TCP, even when the client is running on the same machine as the server container. Find the IP address that has been assigned to the container:
What is _file in Docker?
As an alternative to passing sensitive information via environment variables, _FILE may be appended to the previously listed environment variables, causing the initialization script to load the values for those variables from files present in the container. In particular, this can be used to load passwords from Docker secrets stored in /run/secrets/<secret_name> files. For example:
Why is MySQL forked?
Being a fork of a leading open source software system, it is notable for being led by the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle. Contributors are required to share their copyright with the MariaDB Foundation.
What happens if a container is not initialized?
While this is the expected behavior, this means that it will not accept incoming connections until such initialization completes. This may cause issues when using automation tools, such as docker-compose, which start several containers simultaneously.
What is Docker's main component?
Docker works in something called a client-server architecture. The main component that handles all your containers, volumes, networks, etc is the docker daemon that runs in the background. The docker command is nothing but the client application.

Finding The Defaults File
- To enable MariaDB to listen to remote connections, you need to edit your defaultsfile. See Configuring MariaDB with my.cnffor more detail. Common locations for defaults files: You can see which defaults files are read and in which order by executing: The last line shows which defaults files are read.
Editing The Defaults File
- Once you have located the defaults file, use a text editor to open the file andtry to find lines like this under the [mysqld] section: (The lines may not be in this order, and the order doesn't matter.) If you are able to locate these lines, make sure they are both commented out(prefaced with hash (#) characters), so that they look like this: (Again, the order of these lines don't matter) Alternativ…
Granting User Connections from Remote Hosts
- Now that your MariaDB server installation is setup to accept connections fromremote hosts, we have to add a user that is allowed to connect from somethingother than 'localhost' (Users in MariaDB are defined as 'user'@'host', so'chadmaynard'@'localhost' and 'chadmaynard'@'1.1.1.1' (or'chadmaynard'@'server.domain.local') are different users that can havecompletely different pe…

Caveats
- If your system is running a software firewall (or behind a hardware firewall or NAT) you must allow connections destined to TCP port that MariaDB runs on (by default and almost always 3306).
- To undo this change and not allow remote access anymore, simply remove the skip-bind-address line or uncomment the bind-address line in your defaults file. The end result should …
