how to update portainer with code examples

Portainer is a widely used Docker container management platform that enables users to deploy, manage, and monitor Docker containers. It offers an intuitive user interface that makes it easy to manage and update Docker containers. It allows the containerized application to be deployed easily and quickly which is a great feature to get started with the Kubernetes.

Updating Portainer to the latest version is essential as it not only adds new features but also fixes various bugs from previous versions. Updating Portainer is a simple process and can be done using different methods such as using docker pull commands, using a docker-compose file, and using the Portainer web UI. In this article, we will discuss how to update Portainer using code examples.

Method 1: Updating Portainer using Docker Pull Command

This method requires you to have Docker installed on your system. Here are the steps to update Portainer using Docker pull command.

Step 1: Stop the current Portainer container:

docker stop <container_id>

Step 2: Pull the latest Portainer image:

docker pull portainer/portainer-ce

Step 3: Start the new Portainer container:

docker run -d -p 8000:8000 -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce

In this method, we have used the docker run command to start the new Portainer container. The –restart always flag ensures that the container restarts automatically if it crashes or is stopped.

Method 2: Updating Portainer using Docker Compose

If you have a Docker Compose file for Portainer, you can easily update it without the need to stop and start the container. Here are the steps to update Portainer using Docker Compose.
