Updating a CDO-Standard SDC Host

Use these instructions if you deployed an SDC using the CDO image.

Procedure

Step 1

Connect to your SDC host using SSH or the hypervisor console.

Step 2

Check the version of your Docker service by running this command:

docker version

Step 3

If you are running one of the latest virtual machines (VMs) you should see output like this:

 > docker version
Client:
     Version: 18.06.1-ce
     API version: 1.38
     Go version: go1.10.3
     Git commit: e68fc7a
     Built: Tue Aug 21 17:23:03 2018
     OS/Arch: linux/amd64
     Experimental: false

It's possible you may see an older version here.

Step 4

Run the following commands to update Docker and restart the service:

> sudo yum update docker-ce
> sudo service docker restart

Note	There will be a brief connectivity outage between CDO and your devices while the docker service restarts.

Step 5

Run the docker version command again. You should see this output:

> docker version
Client:
    Version: 18.09.2
    API version: 1.39
    Go version: go1.10.6
    Git commit: 6247962
    Built: Sun Feb XX 04:13:27 2019
    OS/Arch: linux/amd64
    Experimental: false

Step 6

You are done. You have now upgraded to the latest, and patched, version of Docker.
