This chart bootstraps a Visual Studio Team Services agent pool on a Kubernetes cluster using the Helm package manager.
- Kubernetes 1.8+ or newer
The following tables lists the configurable parameters of the vsts-agent
chart and their default values.
Parameter | Description | Default |
---|---|---|
image.repository |

image.tag |
Specify image tag | latest |
image.pullSecrets |
Specify image pull secrets | nil (does not add image pull secrets to deployed pods) |
image.pullPolicy |
Image pull policy | Always |
replicas |
Number of vsts-agent instaces started | 3 |
resources.disk |
Size of the disk attached to the agent | 50Gi |
resources.storageclass |
Specify storageclass used in kubernetes | default |
vstsAccount |
VSTS account name | nil (must be provided during installation) |
vstsToken |
VSTS personal access token | nil (must be provided during installation) |
vstsPool |
VSTS agent pool name | kubernetes-vsts-agents |
vstsAgentName |
VSTS agent name | $HOSTNAME |
vstsWorkspace |
VSTS agent workspace | /workspace |
extraEnv |
Extra environment variables on the vsts-agent container | nil |
cleanRun |
Kill and restart vsts-agent container on completion of a build (completely resets the environment) | false |
volumes |
An array of custom volumes to attach to the vsts-agent pod | docker-socket to mount /var/run/docker.sock (if you still need this volume when defining addition ones, please ensure you reference it again in your list) |
volumeMounts |
volumeMounts to the vsts-agent container as referenced in volumes |
A read-only docker-socket to mount as /var/run/docker.sock in vsts-agent container (as in volumes please reference this again if you still need it in your custom list) |
extraContainers |
Array of additional sidecar containers to add into the vsts-agent pod | nil |
Before starting the chart installation, you have to configure your VSTS instance as follows:
-
Create a personal access token with the authorized scope Agent Pools(read, manage) following these instructions. You will have to provide later the base64 encoded value of this token to the
vstsToken
value of the chart. -
Create a new queue and agent pool with the name
kubernetes-vsts-agents
. You can find more details here.
The chart can be installed with the following command:
export VSTS_TOKEN=$(echo -n '<VSTS TOKEN>' | base64)
helm install --namespace <NAMESPACE> --set vstsToken=${VSTS_TOKEN} --set vstsAccount=<VSTS ACCOUNT> --set vstsPool=<VSTS POOL> -f values.yaml vsts-agent .
Your deployment should look like this if everything works fine:
kubectl get pods --namespace <NAMESPACE>
NAME READY STATUS RESTARTS AGE
vsts-agent-0 1/1 Running 0 1m
vsts-agent-1 1/1 Running 0 1m
vsts-agent-2 1/1 Running 0 1m
A deployed chart can be upgraded as follows:
export VSTS_TOKEN=$(echo -n '<VSTS TOKEN>' | base64)
helm upgrade --timeout 900 --namespace <NAMESPACE> --set vstsToken=${VSTS_TOKEN} --set vstsAccount=<VSTS ACCOUNT> --set vstsPool=<VSTS POOL> -f values.yaml vsts-agent . --wait
This command will upgrade the exiting chart and wait until the deployment is completed.
The chart can be uninstalled/deleted as follows:
helm delete --purge vsts-agent
This command removes all the Kubernetes resources associated with the chart and deletes the helm release.
You can validate the chart during development by using the helm template
command.
helm template .
The number of VSTS agents can be easily increased to 10
by using the following command:
kubectl scale --namespace <NAMESPACE> statefulset/vsts-agent --replicas 10
