Hi guys, its possible to install with help just a part of datahub, like de frontend or gsm (not all the components)?

You want to re-deploy? Because for successfully running DataHub we need all componenets. Which components are you thinking of leaving out?

well de gms, i mean, i need to update the values.yaml so i need to re deploy the gms-service, or to install from local the datahub

You are using helm to deploy to google GKE, right? You can edit the values yaml and do helm deploy. It will only update what is required

but when i do helm install datahub datahub/datahub is not from the local environment, and if i use -f values.yaml is not the yaml from datahub-gms

What do you mean it is not yaml from datahub-gms? You know that there is going to be a single values yaml file when you are deploying helm chart, right? Similar to this one https://github.com/acryldata/datahub-helm/blob/master/charts/datahub/values.yaml

@few-air-56117 the values.yaml that you input into the main helm contains the datahub-gms subchart inside it. i.e. if you edit whatever is under

datahub-gms:

it will get propagated into the datahub-gms subchart. So you can set (for instance),

datahub-gms:  
  ...
  extraVolumes:
    - name: user-props
      secret:
        secretName: datahub-pass-secret
  extraVolumeMounts:
    - name: user-props
      mountPath: /datahub-frontend/conf/user.props
      subPath: token
      readOnly: true

got it, i instaled datahub with -f values.yaml, and the value from conf.user.pros is changed

You need to restart frontend. You can kill the running frontend pod. Sometimes when the secrets are updated the pods are not updated until new pod is created

i tried

kubectl -n default delete po YOUR_POD_NAME ( gms pod)

but its the same result

I was wrong. This should be in frontend https://datahubproject.io/docs/how/auth/jaas/ not gms

now make sens :))

Hi I stumbled upon the same problem. I try to create the secret by using this command

kubectl create secret generic datahub-pass-secret --from-file=user.props

but resulting an error:

Error: failed to start container "datahub-frontend": Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:545: container init caused: rootfs_linux.go:76: mounting "/var/lib/kubelet/pods/0e859469-c55d-4c7e-b746-bba1d4d021ef/volume-subpaths/user-props/datahub-frontend/0" to rootfs at "/datahub-frontend/conf/user.props" caused: mount through procfd: not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

do you know why?

hi @nice-memory-81320 try this one

kubectl create secret generic  datahub-pass-secret --from-literal=token=datahub:<your_pass>

Can you try something like

kubectl create secret generic  datahub-pass-secret --from-literal=token=datahub:password\ntoken=aseem:aseemPassword

sure

Can you try something like this, mount this and let me know if this works

> cat user.props
datahub:datahub
aseem:aseem
> cat user.props | base64

> kubectl create secret generic  datahub-pass-secret --from-literal=token=ZGF0YWh1YjpkYXRhaHViCmFzZWVtOmFzZWVtCg==

sure

Did you restart frontend after updating the secret?

i used helm install

And if you go to frontend pod and check the content of the file user.props what is the content?

ZGF0YWh1Yjp0ZXN0ZHJhZ29zCmRyYWdvczp0ZXN0ZHJhZ28=E0111 123730.124719  83765 v3.go:79] EOF

If you check

kubectl edit secret datahub-pass-secret

something like this

apiVersion: v1
data:
  token: ZGF0YWh1YjpkYXRhaHViCmFzZWVtOmFzZWVtCg==
kind: Secret
metadata:
  creationTimestamp: "2022-01-11T10:34:16Z"
  name: datahub-pass-secret
  namespace: default
  resourceVersion: "5103849"
  selfLink: /api/v1/namespaces/default/secrets/datahub-pass-secret
  uid: a3c0882e-c4ea-4003-b005-975083d0c4c7
type: Opaque

should show up. Is the token correct in here?

hmm, thi sis the token in secret WkdGMFlXaDFZanAwWlhOMFpISmhaMjl6Q21SeVlXZHZjenAwWlhOMFpISmhaMjg9

It got double encoded base64

yea

Can you try this

kubectl create secret generic datahub-pass-secret --from-file=token=user.props

yep , its work from file

you should go through this

sure, i will watch, thx 😃
