Update WordPress plugins via CLI.

Here is a detailed step-by-step procedure to Update WordPress Plugins via the WP CLI on your WordPress instance:

Step 1: Preparing for the Update

1.1 Understanding the Update Process

To avoid potential errors caused by request timeouts or firewall configurations, updates are executed using the WP CLI..

1.2 Strategy for Applying Updates

Adopt a strategy to apply updates one at a time to prevent health checks from failing for an extended period. If the health checks fail for too long, the load balancer might terminate the instance applying the updates, causing the installation to get stuck in maintenance mode.

Step 2: Initiating SSH onto the WordPress Instance

2.1 Accessing the WordPress Instance

In this example I will be connecting to a WordPress container running on AWS Fargate (ECS).

Connect to the WordPress instance via SSH using the following credentials: There is a detailed procedure here to SSH onto ECS.

  • Container: wordpress
  • User: www-data

2.2 Using the Session Manager Plugin

Ensure that the Session Manager plugin has been successfully installed and use the AWS CLI to initiate a session. You will see a message similar to the following:

Bash
Starting session with SessionId: ecs-execute-command-xxxxx www-data@ip-10-X-X-X:~/html$

Step 6: Post-Update Cleanup

6.1 Monitoring the Health Checks

Monitor the health checks to ensure they do not fail for too long to prevent the load balancer from terminating the instance.

6.2 Exiting Maintenance Mode (if necessary)

If the installation gets stuck in maintenance mode, use the CLI to clear it and resume normal operations.
