Unable to install ECS container for Data Services

Nghia — Tue, 21 Apr 2026 07:54:58 GMT

Hello all,

I am installing Data Services with Embedded Container Service. There are 2 dedicated servers: 1 ECS server, 1 ECS agent. First installation run not good, always stuck at this task:

Waiting for process rke-wait

+ kubectl taint node -l ecs_role=master node-role.kubernetes.io/control-plane-
taint "node-role.kubernetes.io/control-plane" not found
taint "node-role.kubernetes.io/control-plane" not found
+ true
+ sleep 10
+ /var/lib/rancher/rke2/bin/kubectl --kubeconfig /etc/rancher/rke2/rke2.yaml get nodes -o 'jsonpath={range .items[*]}{@.metadata.name}:{range @.status.conditions[*]}{@.type}={@.status};{end}{end}'
+ grep Ready=True
++ hostname -f
+ grep instance-20220615-1150.subnet06081614.vcn06081614.oraclevcn.com
+ echo ...
+ [[ ! -z true ]]
+ kubectl taint node -l ecs_role=master node-role.kubernetes.io/control-plane-
taint "node-role.kubernetes.io/control-plane" not found
taint "node-role.kubernetes.io/control-plane" not found
+ true

Anyone face this familiar issue before? how can i fix it?

Any advise is good for me

Thanks in advance

I resolve this problem by reinstallation. Check java 11, selinux, hostname, etc,.. And now all services is up. But I cannot register environment, on monitoring dashboad in Management console, there is a alert: KubeJobFailed: Job cdp/cli failed to complete. So I check log on pod run cdp-cli, and it show:

HTTPSConnectionPool(host='console-cdp.apps.apps.katalyst.vn', port=443): Max retries exceeded with url: /api/v1/environments2/createPrivateEnvironment (Caused by NewConnectionError('<cdpcli.cdprequest.CdpHTTPSConnection object at 0x7f7fabbd5250>: Failed to establish a new connection: [Errno -2] Name or service not known'))

Any advise is good for me

Thanks in advance

This issue is about DNS configuration. Kubernetes dns and my cloud dns is weird. So i have setup a dedicated server for DNS. And it is now good. I also deploy ML workspace successfully. But i got errors with CDE service: unmounted volumes=cm-root-ca-cert because configmap \"clientconfigs-default-tls-pem\" not found

So again, Any advice would be appreciated greatly 😄
