Container Management

Introduction

This section will outline the steps necessary to patch and maintain the CMS software delivered as containers.


UpdatePatch ContainersDocker Host

Purpose
PullDeploy the latest versionupdated ofto the CMS.Docker host itself.

Permission Level
Docker Host Administrator

Notes

  • You will likely need to enable the firewall ruleset that allows SSH access into the Docker host.

Steps

Step

Instructions

Notes

1

Connect to Azure and enable the NSG rule for the Docker Host.

See the configuration table for details.

2

Connect via SSH to the host.

SSH credentials are stored separately.

3

Execute sudo apt update

Will update the package lists.

4

Execute apt list --upgradable

Will show you any updates.

5

Execute sudo apt upgrade -y

Force all components to update.

6

Execute sudo reboot

Reboot.

7

Execute cd /mnt/cms

Change into the folder containing the docker compose file.

8

Execute docker ps -a

If containers are not started, run the docker compose up -d command as needed.

 

There is the potential for a dependent container to still be booting.

 

If necessary, execute docker logs [container name].

3

Execute cd /mnt/cms

Change into the folder containing the docker compose file.

4

Execute docker compose down

This will stop and remove all currently running components.

5

Execute docker compose pull

This command forces Docker to check all required images in the Docker compose file and pulls the latest version.

6

Execute docker compose up -d

This will use the docker-compose.yml file to rebuild the server, this includes loading in the updated appsettings.json files.

7

Execute docker ps -a

If containers are not started, rerun the command above.

 

There is the potential for a dependent container to still be booting.

 

If necessary, execute docker logs [container name].

8

Execute docker system prune -a

This will clean up old containers and networks and keep the system clean and healthy.
