Overview

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 Deployment Events

oc describe dc <dc-name>

Create a New Deployment

Create a New Deployment with oc new-app

oc new-app

Create a New Deployment Manually

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.

For more details on concepts related to pod placement, see:

Pod Placement

Turn Off Auto-Deployment After Build

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

Deleting a Deployment Configuration

oc delete dc/<dc-name>

Deleting a deployment configuration will also automatically delete the replication controllers generated by that deployment configuration.

Scaling Down a Deployment

oc scale dc/sonar --replicas 0
oc scale dc/sonar-postgresql --replicas 0
