Easy Docker management with Portainer
Manage Docker containers from a Docker container
Hi everyone!
In the Django series, we've been using Docker to build our infrastructure. While managing everything through the CLI is a valuable skill, sometimes a user-friendly GUI can be a big help with certain tasks.
And that's where our chosen GUI manager comes in: Portainer.
What is Portainer?
Portainer is a web based Docker manager. It can manage local daemon instances -our local development machine- or remote instances.
Just like any other software, Portainer itself can be conveniently installed and run within a Docker container.
What can I do Portainer?
Portainer provides a central hub for managing all the components within your Docker environment. This includes:
Containers: The individual running instances of applications.
Images: The blueprints used to create containers.
Stacks (Docker Compose stacks): Groups of related containers managed as a single unit.
Networks: How containers communicate with each other.
Volumes: Persistent storage used by containers.
Portainer goes beyond just viewing these elements. It also allows you to perform various actions on running containers, such as:
Entering the container's shell for direct control.
Viewing container logs for troubleshooting.
Monitoring container performance metrics like CPU and memory usage.
Installation as a Docker container
The installation is extremely easy:
When the command finalices, you can access to Portainer with this URL:

Among the Python and Docker posts, I will also write about other related topics (always tech and programming topics, I promise... with the fingers crossed), like:
Software architecture
Programming environments
Linux operating system
Etc.
If you found some interesting technology, programming language or whatever, please, let me know! I'm always open to learning something new!
