"SSH could not read data: Error waiting on socket" when using libgit2 #439

squaremo · 2021-07-13T16:30:05Z

This is reported in the logs:

{
  "level": "error",
  "ts": "2021-07-01T07:44:10.656Z",

}

.. though apparently not all the time, as

After adding [update markers], Image Automation controller started to update files for me.

Source controller reportedly manages to clone the repo (all the time?) when set to use libgit2, and changing to an RSA key didn't stop the error messages. EDIT: no, not all the time -- source-controller also fails intermittently, indicating that the problem is in the code in source-controller/pkg that source-controller and image-automation-controller both use.

The text was updated successfully, but these errors were encountered:

rjhenry · 2021-07-16T11:37:03Z

I've found a solution that worked for me, at least - there gitrepo definition had a URL ending in .git; removing this then worked.
Before: .spec.url: ssh://[email protected]/orgname/repo.git
After: .spec.url: ssh://[email protected]/orgname/repo

Why it worked, I'm not sure - but I happened to stumble across the difference between a working and a non-working cluster.

morganchristiansson · 2021-07-29T19:08:05Z

I am getting this cloning from localhost git repo with openssh+gitolite.

It's not transient every time error waiting on socket.

Same GitRepository works perfectly from source-controller. In image-automation-controller this error:

Why it worked, I'm not sure - but I happened to stumble across the difference between a working and a non-working cluster.

I think this is a significant red herring; a few instances now with the .git-less syntax still hangs. The repository is about 20M and the cluster has a gig pipe to the internet, so it shouldn't be a timeout when trying to clone.

Is it possible to get the image-automation-controller to die in the event of these errors so the scheduler can simply recreate it?

rjhenry · 2021-09-03T08:16:55Z

For the record, this occurs with both libgit2 and go-git gitImplementationson the gitRepository resource; I've switched back to go-git as the source controller seemed much happier with that.

morganchristiansson · 2021-09-03T14:53:45Z

Are there any suggestions on how to debug this further? Any flags to enable debug logging? Or maybe tcpdump?

ozlotusflare · 2021-09-07T12:01:24Z

Hey everyone!
After upgrade FluxCD2 to the latest version I faced with the same issue :(
I checked gitRepository CRD and by default is go-git gitImplementationson, I've tried to change to libgit2, but still have errors:

{
  "level": "error",

Any thoughts , how to fix this ?
Thanks 🙏

I was taking a look at this, and it appears that only way to enable debug logging is to edit the deployment of the image-automation-controller. It's a relatively simple change - in your gotk-components.yaml, make the following change:

@@ -5235,7 +5235,7 @@ spec:
       - args:
         - --events-addr=http://notification-controller/
         - --watch-all-namespaces=true

+        - --log-level=debug
         - --log-encoding=json
         - --enable-leader-election
         env:

I'm now running this in a couple of clusters, so hopefully will get more information that can be contributed to this issue.

squaremo · 2021-09-09T14:03:17Z

For the record, this occurs with both libgit2 and go-git gitImplementationson the gitRepository

image-automation-controller always uses libgit2 for cloning, mainly because the go-git implementation does a shallow clone (and this makes branching difficult to impossible). Did source-controller have any problems when you switched the implementation to libgit2? I gather not -- that's what makes this truly mysterious, because it is running the same code.

rjhenry · 2021-09-09T16:51:55Z

I thought there were issues with both the image automation controller and the source controller, but I've dug through our logging server and found records at the time the change was made. It looks like the problems were with the image-automation-controller, which was immediately failing to clone the repository just minutes after the change was merged. It appears to be the same issue as before, just immediate rather than after some delay.

squaremo · 2021-09-09T17:24:48Z

which was immediately failing to clone the repository just minutes after the change was merged.

Which change was merged -- did I miss a vital clue?

rjhenry · 2021-09-10T14:38:33Z

which was immediately failing to clone the repository just minutes after the change was merged.

Which change was merged -- did I miss a vital clue?

Sorry, that's my own terrible wording - the change was from go-git to libgit2 for the gitImplementation on my gitRepository objects.

rjhenry · 2021-09-15T09:00:51Z

@squaremo If it's any use, I can provide debug-level logs from a controller pod - I'd prefer to do so directly via Slack, though, as I'm not entirely comfortable posting unredacted logs on a public issue.

Worth a try! I'm Michael Bridgen in CNCF slack.

squaremo · 2021-09-16T15:28:24Z

OK, thanks to lots of digging through logs from @rjhenry, I think we have established that this happens for source-controller as well, when the GitRepository object has gitImplementation: libgit2[1]. It seems to be less frequent in the source-controller, but it's already intermittent with image-automation-controller[2] so difficult to judge.

[1] the same "SSH could not read data: Error waiting on socket" error message appears in the source-controller logs, inside a period when the GitRepository was known (in git history!) to have that setting
[2] the image-automation logs show a failure, then a success, without a config change in the meantime

morganchristiansson · 2021-09-22T14:48:55Z

It's started working for me.. debug logging was really helpful.

Ran into next issue -have to put resources in same namespace as GitRepository fluxcd/image-automation-controller#159

squaremo · 2021-09-23T09:14:41Z

It's started working for me.. debug logging was really helpful.

What changed so that it started working? How was the debug logging helpful? Don't leave us hanging @morganchristiansson :-P

morganchristiansson · 2021-09-23T09:50:32Z

I'm still sporadically getting the same error.

{"level":"error","ts":"2021-09-23T09:38:29.217Z","logger":"controller.gitrepository","msg":"Reconciler error","reconciler group":"source.toolkit.fluxcd.io","reconciler kind":"GitRepository","name":"flux-system","namespace":"flux-sy

Because of my namespace issue linked above the automations were correct but not applying anything - with log level debug I was figured this out, I shoud've been able to see this with default info log level too..

I also looked with wireshark/tcpdump but I was only seeing successful ssh connections...

So I haven't really solved the problem just discovered it's working with the error...

rjhenry · 2021-10-04T10:47:07Z

Very similar situation here; on a different cluster I administer we had a successful automation. Taking a look at the logs shows (neatly formatted for your viewing pleasure):

No changes were made to the controller, GitRepository, or really anything else in that time.

hiddeco · 2021-10-09T11:41:13Z

You all may want to try out the the latest release of the source-controller (v0.16.0) and image-automation-controller (v0.15.0), as this contains libgit2 linked against OpenSSL and LibSSH2. Based on my research and extensive testing, this should solve most issues around private key formats and/or SSH transports, with an exception for ECDSA* related host key issues (which will be solved once we depend on libgit2 >=1.2.0).

timja · 2021-10-13T14:59:32Z

@hiddeco

We're still seeing this with:

ghcr.io/fluxcd/helm-controller:v0.12.0
ghcr.io/fluxcd/image-automation-controller:v0.15.0
ghcr.io/fluxcd/image-reflector-controller:v0.12.0
ghcr.io/fluxcd/kustomize-controller:v0.15.5
ghcr.io/fluxcd/notification-controller:v0.17.1
ghcr.io/fluxcd/source-controller:v0.16.0

ssh destination is github.com

hiddeco · 2021-10-14T17:45:18Z

@timja we have a suspicion this is due to underlying C objects not getting freed in time; but given the undocumented state of libgit2/git2go, this is very much guess work.

I created #452, which most importantly frees the Repository object which is responsible for the lifetime of the connection, which should ensure any previous connections are properly cleaned up.

It would be great if you could give this a test run, as the issue is kind of hard to replicate for us. (If you prefer testing it using the image-automation-controller, please shout, as I can port the changes to such a test image as well).

rjhenry · 2021-10-18T15:30:24Z

@hiddeco If you could port the same changes over to the image-automation-controller, that'd be great - I'd be keen to test this out for you.

hiddeco · 2021-10-18T19:28:17Z

@rjhenry thanks a lot! 🙇🥇 Did a quick port, and the image details can be found at fluxcd/image-automation-controller#238

Can we provide anything else to help?

hiddeco · 2021-10-19T09:45:48Z

After having cloned the repository myself, I now have the suspicion it's due to size. Even on my 1Gbps connection, it seems to be relatively slow (but I think the default timeout is 30s 🤔).

Hi, no errors for almost 2 days

uderik · 2022-04-03T14:21:43Z

Over a time image-automation-controller:0.21.3, can't connect to GitLab with error:
unable to clone 'ssh://git@gitlabhost/gitops/my-gitops': transport close (potentially due to a timeout)
after pod restart, it's return to normal work

pjbgf · 2022-04-04T11:11:19Z

@uderik did it stop working after the error? IAC should be able to self-heal from such issue and just carry on business as usual.

What's the interval you currently have set for the repository that had the issue?

peterfication · 2022-04-04T13:12:35Z

I had the same issue and tried the new version with the EXPERIMENTAL_GIT_TRANSPORT set to true and now there are no errors for me anymore as well 💪

source-controller: 0.22.5
image-automation-controller: 0.21.3

uderik · 2022-04-04T13:36:54Z

@pjbgf on two clusters (us-east-1 and ap-southeast-1) same issue, many errors with transport close (potentially due to a timeout) and no updates
on another cluster (eu-central-1) see pod restarts with last error:

[signal SIGSEGV: segmentation violation code=0x80 addr=0x0 pc=0x16f19c0]
runtime stack:
runtime.throw({0x1da3c46, 0xc0008dc8f8})
        runtime/panic.go:1198 +0x71

maybe it has something to do with the location of the clusters , gitlab location eu-central-1

gitrepo interval 1min, timeout 2min

@pjbgf CrashLoopBackOff log in attach,It works but has already crashed 4 times (in 13 hours) with this errors, on all 3 envs, where i updated images for source/image-automation deployments
image-automation-controller.log

pjbgf · 2022-05-12T14:12:50Z

@uderik thanks again for sharing. I managed to reproduce and on my environment the changes seem to have fixed the problem. The new version have some changes we recently merged into main, which would recover git2go/libgit2 panics. Therefore if this would happen again you would see errors on the logs, but no crashes/restarts.

The PR is now updated and a new image created for source-controller:
ghcr.io/fluxcd/source-controller:rc-6d517589

Please let me know how you get on.

UPDATE: changed the image with an official source-controller release candidate.

Using

ghcr.io/fluxcd/image-automation-controller:v0.22.1

on GKE results in the same error. Surprisingly it was working for some days without any change. Source is Gitlab.

pjbgf · 2022-05-17T18:10:11Z

@Nosmoht occurrences of this issue tend be intermittent and resolve itself. We have a few changes that should be released soon which should decrease their likelihood. On they are merged/released I will share on this thread.

Nosmoht · 2022-05-23T10:08:02Z

@pjbgf any idea when a new release will be published?

pjbgf · 2022-05-24T13:55:51Z

@Nosmoht We are aiming to have a release done between the end of this week and beginning of next.

pjbgf · 2022-05-27T14:01:44Z

@uderik @Nosmoht here's the release candidate for source controller: ghcr.io/fluxcd/source-controller:rc-4b3e0f9a

Can you please give it a go and let me know whether it resolved your issues?

quay.io/paulinhu/image-automation-controller:v0.22.2-cacheless seems to have resolved the issue for me.

Nosmoht · 2022-06-02T07:12:29Z

Just tried with quay.io/paulinhu/image-automation-controller:v0.22.2-cacheless but still get the same issue.

unable to clone '#####'
SSH could not read data: Error waiting on socket

Hi @Nosmoht, we are in the process of getting some improvements merged, which should fix this. Could you try this image ghcr.io/fluxcd/image-automation-controller:rc-48bcca59 and confirm whether it solves the issue for you?

Nosmoht · 2022-06-02T08:24:43Z

Hi @aryan9600,

tried, SSH error replaced by following:

{"level":"error","ts":"2022-06-02T08:22:41.221Z","logger":"controller.imageupdateautomation","msg":"Reconciler error","reconciler group":"image.toolkit.fluxcd.io","reconciler kind":"ImageUpdateAutomation","name":"app","namespace":"flux-system","error":"unable to fetch-connect to remote 'ssh://[email protected]/app/app.git': ssh: handshake failed: hostkey could not be verified"}

Seems like i need Gitlab's SSH key inside the container. Any easy way to do that? I bootstrap Flux with Terraform using Flux provider.

aryan9600 · 2022-06-02T08:49:06Z

I'm not familiar with the terraform provider, but the GitRepository source needs to have a .spec.secretRef, which provides a reference to the secret containing the private key and the password. You can create one using the cli: https://fluxcd.io/docs/cmd/flux_create_secret_git/

Nosmoht · 2022-06-02T13:46:25Z

Hi @aryan9600,

as it is the flux-system Gitrepository it already uses the flux-system secret which contains identity, identity.pub and known_hosts already.

jakubhajek · 2022-06-07T09:15:23Z

hello Flux Maintainers!,

Thanks a lot for your great work!

I wanted to let you know that this issue can be closed and it is solved with the latest Flux 0.31.0 release. I have already tested the latest release and seems that I no longer experience the issue in all of my environments.

uderik · 2022-06-09T21:33:56Z

Look's like it's really fixed now, many thanks
