Check the presence of the images after releasing #550

          **Unrelated:** I think we should also check the presence of the images after releasing. Just to double check. Do you think this check should be part as the release process @wallrj?

To check that the automation went through, check that the 3 public images are available:

docker run -it quay.io/jetstack/preflight:v0.1.49 version
docker run -it quay.io/jetstack/venafi-agent:v0.1.49 version
docker run -it registry.venafi.cloud/venafi-agent/venafi-agent:v0.1.49 version

Then, you will need to use venctl to check the two private registries:

1. curl -sSfL https://dl.venafi.cloud/venctl/latest/installer.sh | bash
   

2. Go to https://ven-tlspk.venafi.cloud/platform-settings/user-preferences?key=api-keys. Log in using the username admin0@tlspk.qa.venafi.io and the password here). Copy the API key for the next step (click "Generate" if the API key doesn't already exist).

3. Set the APIKEY env variable:

   APIKEY=...
   

4. Docker login to private-registry.venafi.cloud:

   venctl iam service-account registry create --name "$USER Temp" \
     --vcp-region US \
     --output dockerconfig \
     --output-file dockerconfig \
     --api-key $APIKEY
   docker login private-registry.venafi.cloud \
     | --username $(cat dockerconfig | jq '.. | select(.username?).username' -r) \
     | --password $(cat dockerconfig | jq '.. | select(.username?).auth            | @base64d' -r | cut -d: -f2) |

5. Go to https://ven-tlspk-eu.venafi.cloud/platform-settings/user-preferences?key=api-keys. Log in using the username admin0@tlspk.qa.venafi.io and the password here). Click "Generate" and copy the API key for the next step.

6. Set the APIKEY env variable:

   APIKEY=...
   

7. Docker login to private-registry.venafi.eu:

   venctl iam service-account registry create --name "$USER Temp" \
     --vcp-region EU \
     --output dockerconfig \
     --output-file dockerconfig \
     --api-key $APIKEY
   docker login private-registry.venafi.eu \
     | --username $(cat dockerconfig | jq '.. | select(.username?).username' -r) \
     | --password $(cat dockerconfig | jq '.. | select(.username?).auth            | @base64d' -r | cut -d: -f2) |

And now:

docker run -it private-registry.venafi.cloud/venafi-agent/venafi-agent:v0.1.49 version
docker run -it private-registry.venafi.eu/venafi-agent/venafi-agent:v0.1.49 version
