Demystifying MySQL User Management (Part 1)

Managing user accounts can be a bit confusing, when working with MySQL. The two main commands in that context: CREATE USER and GRANT. Obviously, CREATE user is for adding a new user while GRANT is used for assigning permissions. Pre-requisits: Docker Compose For testing access to a MySQL instance, we can use Docker for running said instance and two different client containers. The docker-compose snipped below orchestrates those three containers and puts them on a shared network.

Jupyter docker stacks with a custom user

Jupyter allows to set a custom user instead of**_jovyan_** which is the default for all containers of the [Jupyter Docker Stack][1]. You need to change this user or its UID and GID in order to get the permissions right when you mount a volume from the host into the Jupyter container. The following steps are required: Create an unprivileged user and an asociated group on the host. Here we call the user and the group docker_worker Add your host user to the group.
