[dove-young]

Summary

1. I am walking through the quick start at here https://concourse-ci.org/tutorial-resources.html#put-steps. my pipeline cannot check this git resouce via ssh protocal.
   I got following error at http://localhost:8080/teams/main/pipelines/hello-world-git-failed/resources/repo-ssh page

Error loading key "/tmp/git-resource-private-key": error in libcrypto

2. when I change resource uri to https protocol, I can get git repo been cloned, but I cannot make a commit to it.

resources:
- name: repo
type: git
source:
  uri: https://github.com/dove-young/concourse-examples.git
  # specify branch because it's required for the put step
  branch: master
  username: dove-young
  password: <my password>

Then I got error like this in repo-ssh step.

fatal: could not read Username for 'https://github.com': No such device or address

Triaging info

• Concourse version:
• Browser (if applicable):
• Did this used to work?

[dove-young]

I can workaround the problem 2 by adding username and password in uri, like this

source:
  uri: https://dove-young:<my-password>@github.com/dove-young/concourse-examples.git

but this will be rejected by github with this message

Support for password authentication was removed on August 13, 2021

To workaround this, I need to replace <my-password> to my personal access token. Then it works.

For using the key, please make sure the format of the key and you can actually use the key the get access to github in your local env.
