Hi team, I have one question about using service account to deploy service. To use S3 as blockstore, before my helm config file is like below
Copy code
secrets:
  authEncryptSecretKey: "123"
  # Use the following to fetch PostgreSQL connection string from an existing secret:
  databaseConnectionString: "postgres://***"

lakefsConfig: |
  database:
    type: "postgres"
  blockstore:
    type: "s3"
    s3:
      region: "us-west-2"
      credentials:
        access_key_id: "***"
        secret_access_key: "***"
If I want to switch to service account to access S3 bucket, do you have any example for the helm config files? Will it be something like below
Copy code
serviceAccount: <service-account-name>
secrets:
  authEncryptSecretKey: "123"
  # Use the following to fetch PostgreSQL connection string from an existing secret:
  databaseConnectionString: "postgres://***"

lakefsConfig: |
  database:
    type: "postgres"
  blockstore:
    type: "s3"
    s3:
      region: "us-west-2"

lakeFS support using credentials-file using the 
blockstore.s3.credentials_file
and `blockstore.s3.profile`configurations. You can give a path to a configuration file that will look something like that:
Copy code
[lakefs]
role_arn = <YOUR_ROLE_ARN>
web_identity_token_file = /var/run/secrets/eks.amazonaws.com/serviceaccount/token
role_session_name = <ROLE_SESSION_NAME>

Thanks for the quick reply! I will have a try to use profile. But serviceAccount is the preferred way for us. I saw the helm values can take serviceAccount value. I guess that’s supported. So trying to get some example to follow
a
@gang ye FYI: I requested engineers to review this request and provide some example to use service account.
g
OK! Thanks a lot!

@gang ye the lakeFS server uses the golang aws sdk. If you configured the service account for the lakeFS pod/deployment properly, it should work out of the box. So this config
Copy code
secrets:
  authEncryptSecretKey: "123"
  # Use the following to fetch PostgreSQL connection string from an existing secret:
  databaseConnectionString: "postgres://***"

lakefsConfig: |
  database:
    type: "postgres"
  blockstore:
    type: "s3"
    s3:
      region: "us-west-2"
will default to aws sdk credentials lookup, which will find the service account creds.

I think I figured out how to config the service account in helm config file like below
Copy code
serviceAccount:
  name: <service-account-name>
🤘 1
one quick question, does lakefs uses AWS 
DefaultAWSCredentialsProviderChain
? after setting service account in helm deployment, pod env variables have the configuration below
Copy code
AWS_DEFAULT_REGION=us-west-2
AWS_REGION=us-west-2
AWS_ROLE_ARN=arn:aws:iam::***:role/data-experimentation
AWS_WEB_IDENTITY_TOKEN_FILE=/var/run/secrets/eks.amazonaws.com/serviceaccount/token
AWS_STS_REGIONAL_ENDPOINTS=regional
But the lakefs server cannot create the block adapter as expected.
Hi @Itai Admi I was able to set the service account in deployment. The pod contains the above env variable. And I verified the service account credential works by running another pod with awscli to list files on S3. But still lakefs server cannot initialize the block adapter. Any other missing configuration? Do you have any clue? Thanks!
i
Hey @gang ye, can you share the lakeFS config that you’re using now, including the env vars for it, if any (starting with 
LAKEFS_
)? Also, can you share the logs from the server?
g
Sure. Helm config file

i
And then does it exit?
g
pod keeps restarting with read probe and liveness probe failure
i
Gotcha. I don’t think it has to do with the block adapter.
Do you have logs from the failing probes?
g
The above log is from the failing pod. Probe it shows
Copy code
Liveness probe failed: Get "<http://172.16.95.57:8000/_health>": dial tcp 172.16.95.57:8000: connect: connection refused
I guess it’s caused by server is not running, so connection won’t work
i
What version are you using? I’ll try to reproduce it
gratitude thank you 1
g
helm version 0.13.3 lakefs image version 0.113.0
I have enabled TRACE log, but there is no very helpful clue from the log. The reason I think it’s related to loading AWS credential(especially for service account case) is, if I set the blockstore to local or set the aws credential(access key, secret key) manually in lakefsConfig, it works.
i
OK, that’s weird. I’m also unable to reproduce at the moment
When the AWS creds are not set properly, lakeFS normally: 1. Exists on startup with the blockstore error 2. Fail to create a repo / perform any data operation on existing repos.
g
any config we can set to enable AWS debug log? looks like 
logging.level
in lakeConfig only enables lakefs server debug log
i
Checking
Yes, can you try this lakeFS config?

Not sure it’s related, but still worth a shot. How many instances of lakeFS pods are you using?
g
only one instance
👍 1
i
Oh, what are the values you’re using for the probes? Did you uncomment the 
livenessProbe
& 
readinessProbe
section in the 
values.yaml
file?
g
I didn’t uncomment the livenessProbe and readinessProbe part.
i
Can you try that? perhaps it takes a bit longer for lakeFS to spinup with the service account.
g
uncomment
Copy code
extraEnvVars:
# Override K8S defaults for readinessProbe
  readinessProbe:
    failureThreshold: 10
    periodSeconds: 5
    successThreshold: 4
    timeoutSeconds: 1
# Override K8S defaults for livenessProbe
  livenessProbe:
    failureThreshold: 20
    periodSeconds: 5
    successThreshold: 4
    timeoutSeconds: 1
    initialDelaySeconds: 5
but there is format issue
if it takes time to spinup service account, then when pod restarts, I think it should work. But what i saw is, it never succeeds.
i
It’s the initialization of the S3 blockstore with service account that takes longer, and that happens with every pod restart. At least that’s my theory..
I think you need to ident it left (no whitespace before 
readinessProbe
& 
livenessProbe
)
g
this is the default value for the probe, I will update it manually in k8s deployment
Copy code
livenessProbe:
            httpGet:
              path: /_health
              port: http
              scheme: HTTP
            timeoutSeconds: 1
            periodSeconds: 10
            successThreshold: 1

I’m out of ideas at the moment. I’ll consult my colleagues and provide an answer early next week. I understand you have a workaround for now, right? (the static creds)
👌 1
g
we don’t have a long existing s3 creds(security rule), only a temp one which will expire every few hours.
i
Got it, so it’s indeed a blocker
g
yeah, thanks very much for help
🙌 1
i
Hey @gang ye Regarding the the credentials, you don’t need to use static credentials. Depends on how you perform auth, we internally run on EKS with IRSA for example and that means that by adding an annotation to the serviceAccount that is attached to the lakeFS Deployment we give it all the permission it needs. It’s basically based on IAM:AssumeRole and there’s no static credentials involved. You can even configure this in the Helm chart itself (including the SA creation) for example, that’s how that part would look in 
values.yaml
Copy code
serviceAccount:
  name: my-svc-acc

extraManifests:
- apiVersion: v1
  kind: ServiceAccount
  metadata:
    name: '{{ .Values.serviceAccount.name }}'
    annotations:

Hi @Isan Rivkin yes, we used service account with right annotation setting. The issue is, once using service account, lakefs server cannot start as expected. Logs are attached earlier.
i
So if I understood correctly the issue is that the liveness probe causes restarts due to some unknown reason (I don’t see anything helpful at the logs) is it correct? • If so can you maybe try and override the container command to “sleep 1d” of lakeFS through the chart and give some infinite amount for the readiness? Then once its up exec into the container and try to to run lakefs? Then outside of the container try to reach it with curl or something like that? • Also, do you have an HTTP Proxy in your environment? • Is the blockstore S3 or some compatible interface?
g
I think, the liveness probe and read probe themselves are not the root cause of the problem. The root cause is lakefs server cannot start when using service account (log message doesn’t provide helpful clue and the blockstore i’m using is S3) And I have used the same service account on other pod to access s3, which works as expected.
i
Could be, let’s explore that option. Can you please make sure that your namespace and service account information is correct. • The the SA needs to be in the same namespace and the N needs to exist before the SA is created. • If you configured it to use a default SA (which I don’t think is your case but just to make sure) - then that has to exist as well, and the SA should be created after the namespace. • Finally, if none of that helps can you please attach the events of the resources? I’m pretty sure we will see the answer there:
Copy code
k describe deploy <lakefs-deploy> 
k describe pod <lakefs-pod> # try to catch pod events before it restarts 
k describe replicaset <lakefs-replicaset> 
k describe sa <your service account> 
k describe svc <lakefs service>

Hi @Isan Rivkin Thanks for following up on the issue. • The the SA needs to be in the same namespace and the N needs to exist before the SA is created. ◦ yes, SA exists in same namespace • If you configured it to use a default SA (which I don’t think is your case but just to make sure) - then that has to exist as well, and the SA should be created after the namespace. ◦ We don’t use default SA. describe deploy

Hey @gang ye thanks for getting back to me and for the patience with the delay in response, it’s due to time zone difference. After Inspecting the additional info you have provided i I have noticed few “suspects” but nothing concrete. 1. First, I must say that if you prefer we can do a short meeting to troubleshoot (see DM). 💻 2. I have released from a branch a lakeFS version (1.0.0) with 1 change: very extensive logging of all the steps in the setup process. That way we can see where it get’s stuck. 🔨 a. Can you please update the Helm Chart values with the docker image 
<http://docker.io/treeverse/experimental-lakefs|docker.io/treeverse/experimental-lakefs>
and tag 
1.0.0-vvv1
(attached full 
values.yaml
below) b. All the logs I added contain the field 
trace_flow=true
, please run the new chart and attach the logs. If possible re-run twice to make sure we don’t crush on random places in the code based on the last log message we will see. 3. Regarding the issue itself: 🕵️‍♂️ the latest logs you sent me, I think that K8S cannot locate runtime dependencies (i.e., the var/run/secrets/kubernetes.io or service account files are missing). a. What K8S Version is the cluster? b. Are you using any special plugins for authentication / authz between pods (i.e calico)? c. This might occur when some containers inside the pod attempt to interact with an API without the default access token. d. I suspect it because the ServiceAccount you attached has values set in 
Mounted Secrets
and that’s an old way of accessing SA tokens. e. If that’s the case it can fix this error by allowing all new mount creations to adhere to the default access level throughout the pod space. Ensure that new pods using custom tokens comply with this access level to prevent continuous startup failures. This can be done with setting 
.Values.podSecurityContext
and 
.Values.securityContext
please refer to this SOF as a nice reference to the values and maybe check other charts you have in the cluster?

Hi @Isan Rivkin Thanks for the detail. I will redeploy with image 1.0.0-vvv1 today and then get back to you to see if we can find any clue. Regarding the issue, we don’t use any special authn authz. For the service account token, I once logged into the pod and I can print it out (var/run/secrets/eks.amazonaws.com/serviceaccount/token) successfully. K8s version
Copy code
kubectl version --short
Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
Client Version: v1.25.9
Kustomize Version: v4.5.7
Server Version: v1.23.17-eks-2d98532
Hi @Isan Rivkin One quick question, does the new image 1.0.0-vvv1 support amd64?
i
I built it specifically for amd64 yes, why?
g
Got it. Then it should work. Our k8s arch is amd64.
