Unable to connect to Github through sync due to UnknownHostKey

[ziegelstein]

Describe the issue

I used the following workflow:

id: test-git-sync-public
namespace: test

tasks:
  - id: git
    type: io.kestra.plugin.git.Sync
    url: git@github.com:username/public-repository.git # Changed for privacy
    branch: main

which resulted in the following error:

2024-04-05 15:30:53.393

UnknownHostKey: github.com. RSA key fingerprint is d5:2c:63:d9:bc:75:9d:de:b1:4e:36:28:9f:7a:9c:39

I also tried to add an password and connect to a private repository, which resulted in the following error:

git@github.com:username/private-repository.git: remote hung up unexpectedly
[ssh://git@github.com:22](ssh://git@github.com/): org.eclipse.jgit.transport.CredentialItem$YesNoType:The authenticity of host 'github.com' can't be established.
RSA key fingerprint is d5:2c:63:d9:bc:75:9d:de:b1:4e:36:28:9f:7a:9c:39.
Are you sure you want to continue connecting?

I discuesed this on Slack and we came to the conclusion to open an bug report for it.

Expected Behaviour:

I can directly connect to github through the git.sync module, or have an option to accept certs when configuring it.

Environment

• Kestra Version: 0.15.10 - kestra/kestra:latest-full
• Operating System (OS/Docker/Kubernetes): Docker version 24.0.5, build 24.0.5-0ubuntu1~23.04.1
• Java Version (if you don't run kestra in Docker):

As said on slack you may have a corrupted ~/.ssh/known_hosts file as I can't reproduce the issue even if deleting it

Hello!

How did you tried to reproduce the issue? After opening the issue, I tried the same flow in an newly created lxc container and vm inside proxmox. They both generate the same result.

I will try this also on bare-metal once I have time. This is either an issue on Proxmox or Kestra, I will update this issue once I have tested more.

I tried locally but erasing my whole known_host file

Hi @ziegelstein, could you try perhaps using the new SyncFlows or SyncNamespaceFiles tasks on the latest version?

• docker pull kestra/kestra:latest
