10 interviews
Make the exact image alpine:3.21 available locally for lumen-5025. Keep the existing web image.
Run parcel-5025 from nginx:1.27, publishing host port 18122 to container port 80. A second service already occupies port 8080.
Start cedar-5025 from nginx:1.27 with host directory /home/learner/workspace/site mounted at /usr/share/nginx/html read-only.
Build cobalt-5026:v1 again without changing files. The dependency COPY layer must come from cache.
Start the supplied compose.yaml services in detached mode. Keep web's host mapping 18125:80, REGION=east, and the cache data volume. Use the service name cache for the dependency.
Scale Deployment parcel-5026 to 4 replicas. Don't scale the unrelated preview service.
Expose Deployment cedar-5026 with a ClusterIP Service named cedar-5026, selector app=cedar-5026, port 80 and targetPort 80. Edit workload.yaml or use an equivalent supported command, then apply the result.
Set ConfigMap cobalt-5027-config with REGION=east and LOG_LEVEL=warn. Store these nonsecret settings as strings. Edit workload.yaml or use an equivalent supported command, then apply the result.
Set Deployment lumen-5027 requests to cpu=150m, memory=192Mi; set limits to cpu=1000m, memory=512Mi. Keep one replica. Edit workload.yaml or use an equivalent supported command, then apply the result.
Both two-replica releases are ready. Switch Service parcel-5027 from track=blue to track=green while retaining app=parcel-5027, port 80 and both Deployments. Save a successful local probe to probe.txt.
