Creating image pull secrets for an instance of IBM Software Hub (Upgrading from Version 5.2 to Version 5.4)

You must create an image pull secret in the projects that are associated with an instance of IBM Software Hub. The image pull secrets ensure that any components that use Helm have access to the credentials for pulling images.

Upgrade phase

Updating your client workstation
Collecting required information
Preparing to run an upgrade in a restricted network
Preparing to run an upgrade from a private container registry
Upgrading prerequisite software
Upgrading shared cluster components
Preparing to upgrade an instance
Upgrading an instance
Setting up IBM Software Hub

Who needs to complete this task?

Instance administrator An instance administrator can complete this task.

When do you need to complete this task?

This task is required.

Repeat as needed If you plan to upgrade multiple instances of IBM Software Hub, you must repeat this task for each instance that you plan to upgrade.

Before you begin

Best practice: You can run the commands in this task exactly as written using the installation environment variables. Ensure that you added the new environment variables from Updating your environment variables script.

In addition, ensure that you source the environment variables before you run the commands in this task.

Procedure

Log in to Red Hat® OpenShift® Container Platform as a user with sufficient permissions to complete the task.
```
${OC_LOGIN}
```
Remember: OC_LOGIN is an alias for the oc login command.

Create a file named dockerconfig.json based on where your cluster pulls images from:

IBM Entitled Registry

cat <<EOF > dockerconfig.json 
{
  "auths": {
    "cp.icr.io": {
      "auth": "${IMAGE_PULL_CREDENTIALS}"
    },
    "icr.io":{
      "auth": "${IMAGE_PULL_CREDENTIALS}"
    }
  }
}
EOF

Private container registry

cat <<EOF > dockerconfig.json 
{
  "auths": {
    "${PRIVATE_REGISTRY_LOCATION}": {
      "auth": "${IMAGE_PULL_CREDENTIALS}"
    }
  }
}
EOF

Create the image pull secret in the operators project for the instance:

oc create secret docker-registry ${IMAGE_PULL_SECRET} \
--from-file ".dockerconfigjson=dockerconfig.json" \
--namespace=${PROJECT_CPD_INST_OPERATORS}

Create the image pull secret in the operands project for the instance:

oc create secret docker-registry ${IMAGE_PULL_SECRET} \
--from-file ".dockerconfigjson=dockerconfig.json" \
--namespace=${PROJECT_CPD_INST_OPERANDS}

If your instance includes tethered projects, create the image pull secret in each project that you plan to tether to the operands project:
```
oc create secret docker-registry ${IMAGE_PULL_SECRET} \
--from-file ".dockerconfigjson=dockerconfig.json" \
--namespace=${PROJECT_CPD_INSTANCE_TETHERED}
```
Repeat this step for each tethered project that is associated with this instance of IBM Software Hub.
Tip: If you set the PROJECT_CPD_INSTANCE_TETHERED_LIST environment variable, print the list of tethered projects to the terminal:
```
echo $PROJECT_CPD_INSTANCE_TETHERED_LIST
```
Use this information to set the PROJECT_CPD_INSTANCE_TETHERED environment variable before you re-run the command.

What to do next

Now that you've created the image pull secrets for this instance of IBM Software Hub, you're ready to complete Upgrading IBM Software Hub (Upgrading from Version 5.2 to Version 5.4).
