rancher updating

To update Rancher, you can follow these steps:

1. Make sure you have a backup of your Rancher server data and configuration.
2. Check the Rancher documentation for the latest version and release notes.
3. Stop the Rancher server by running the following command:

   sudo docker stop rancher

4. Pull the latest Rancher server Docker image by running:

   sudo docker pull rancher/rancher:<latest_version>

Replace `<latest_version>` with the version you want to update to.
5. Start the Rancher server container using the new image by running:

   sudo docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher:<latest_version>

6. Wait for a few minutes for the server to start up and check if everything is working fine.
7. If you are using Rancher HA, repeat steps 3-6 for each of your Rancher server nodes.
8. Once you have verified that the update is successful, you can delete the old Rancher server container by running:

   sudo docker rm -f rancher

Please note that these steps may vary based on your specific setup and configuration. It's always recommended to refer to the official Rancher documentation for the most accurate and up-to-date instructions.
