value.

By default, Coder creates the cache directory in `/home/coder/.cache`. Given the

this directory. To fix this, set the `CODER_CACHE_DIRECTORY` environment variable
to `/tmp/coder-cache`.
OpenShift-provided UID and `readOnlyRootFS` security context constraint, the Coder
container does not have permission to write to this directory.
To fix this, you can mount a temporary volume in the pod and set
the `CODER_CACHE_DIRECTORY` environment variable to that location.

Additionally, create the Coder service as a `ClusterIP`. In the next step,
you will create an OpenShift route that points to the service HTTP target port.
