MongoDB fails to deploy

[dascog]

Hi, I have been looking at this issue for some days and have not been able to resolve it.
Context: "Connecting to a Database" in the National Parks workshop.
Steps:

• Both the "Create Template" and "Import Image" steps seem to work without a problem.
• The "Add Database" step similarly seems to work fine except the when the database deploys it fails to scale up to 1 pod.
  Other info:
• Obviously the app itself doesn't work without a DB
• If you attempt to trigger a scale event by using the "Start Rollout" menu item, a popup appears with the error message: cannot trigger a deployment for "mongodb-nationalparks" because it contains unresolved images
  Platform:
• I am doing this on a 4.10 cluster on AWS VMs.

Hello, I was able to fix this problem by modifying the template since it doesn't really specify the image.

1. Import the 3.6 tag into the ImageStream

   oc import-image mongodb:3.6 --from=registry.access.redhat.com/rhscl/mongodb-36-rhel7 --confirm

2. Make sure it was imported

   oc describe istag mongodb:3.6

3. Finding the image name

   oc get istag mongodb:3.6 -o jsonpath='{.image.dockerImageReference}' && echo

4. Modifying the template

oc set image dc/mongodb mongodb=${FULL_IMAGE_REF}

(4a).Remove any problematic triggers (optional but helpful)

oc set triggers dc/mongodb --remove-all

(4b).Add a proper trigger if you want auto updates

oc set triggers dc/mongodb \
  --from-image=mongodb:3.6 \
  --containers=mongodb \
  --auto

5.Trigger a deployment

oc rollout latest dc/mongodb
