Renew the Docker Certificate
If Docker-based Plant Applications Universal Client machine is shut down during the 90-day interval period, Docker swarm stops working due to certificate expiry. This is a workaround to renew the expired swarm certificates.
Procedure
- Stop the Docker service using the following command:
sudo service docker stop - Modify the system date to a previous date (that is, a date before the certificate expired) using the following command:
sudo date -s “04 Feb 2020 11:00:00” - Start the Docker service using the following command:
sudo service docker start - Generate new certificates using the following command:
sudo docker swarm ca –rotate - Stop the Docker service using the following command:
sudo service docker stop - Set the system date to current time using the following command:
sudo date -s “04 Feb 2020 11:00:00” - Start the Docker service using the following command:
sudo service docker start
