View Deployment Controllers for Project

oc get dc

View the Latest Deployment for a Deployment Controller

oc deploy <deployment-controller-name>

For each on-going deployment, there is a deployment pod, whose name can be inferred from the list of pods for the project:

oc get pods

View Deployment Logs

The log of the deployment can be obtained from the deployment pod:

oc get pods
NAME                 READY     STATUS             RESTARTS   AGE
...
<dc-name>-1-deploy   1/1       Running            0          7m

Then

oc logs -f <dc-name>-1-deploy 

The same log can be obtained from the deployment itself:

oc logs -f dc/<dc-name>

View Deployments for Project

oc get deploy

The deployments returned by this list are backed by deployment pods, which can be retrieved with

oc get pods

View Deployment Logs

View deployment logs for a deployment:

oc logs -f deploy/<deploy-object-name>

Starting a Deployment

oc rollout latest dc/<deploymentconfig-name>

This will start the number of replicas specified in ?

oc scale dc logging-es-3fs5ghyo --replicas=1

scaling the pod instead of the deploymentconfig may modify the deployment config. Verify

Assigning Pods to Specific Nodes

https://docs.openshift.com/container-platform/3.6/dev_guide/deployments/basic_deployment_operations.html#assigning-pods-to-specific-nodes

Assigning a Pod to Nodes that Match a Node Selector

Edit the DeploymentConfig that defines the pod:

oc edit dc/<pod-name>

Inject the node selector specification under

spec:
  ...
  template:
    ...
    spec:
      ...
      nodeSelector:
        keyA: valueA

Restart the corresponding pod, by simply deleting it.

Turn Off Auto-Deployment After Build

oc set triggers dc/<deployment-config-name> --remove-all
