What is Portainer? Learn how Docker can go beyond the front end in LetsCloud


Who does not know well imagines that the routine of those who work with information technology is only a black screen and many lines of codes and commands? However, the truth is that there are currently several tools that transform this type of work into something more visible, understandable and practical. Portainer is an example of this, a frontend developed for Docker but with an excellent graphical interface.

What is Portainer?

Made for those who already work with Docker, but, even so, still need ease to manage their containers, Portainer is more than a tool-free with a very friendly UI.

As the name suggests, “portainer” is a specific type of crane for handling container loading and unloading movements at ports around the world. Due to the similarity of the function performed, the web interface created to operate in the same way in Docker was named Portainer. After all, this emphasizes that its main promise is to take the frontend beyond what we are used to.

What is it for?

Portainer is a container organizer. What’s different is that its UI was designed to make your tasks easier, whether they are clustered or not. It turns code on command lines into a web interface that can create and monitor new containers in the docker’s socket. With that, it can even be used in the visualization of the cluster and all its user access permissions and the like.

With it, you can also connect to multiple clusters, access the shell of containers, migrate stacks between clusters and more, all based on a good intuitive facility.

Where to use Portainer?

It is worth mentioning that the Portainer is not a testing environment, that is, it can be, and is, used for production routines, and is present mainly in large companies. After all, who doesn’t need a Docker UI to make the routine easier?

Among its main features is possible:

  • Manage images in Docker – pull, delete, Build
  • Deploy applications directly from templates
  • Container management – Start, stop, end, restart, pause, continue, remove, create
  • Manage networks – Add, remove, edit
  • Manage volumes – Add, remove, manage permissions
  • Check the docker engine events
  • Add custom docker records and add authentications for the docker hub
  • Create endpoints
  • Add users who can manage Docker
  • Manage Docker swarm
  • Create containers with custom templates
