how to download specific commit of the file on github - github

Given a short sha, I want to be able to download the file content of that commit using the github api.
currently i am using following to fetch the content, and it works fine, but how can i download the content for specific sha?
curl -u 'username:password' \
-H 'Accept: application/vnd.github.v3.raw' \
-o output.yaml
-L https://mycompany/api/v3/repos/myorg/myrepo/contents/services/serviceA/helm/manifest.yaml

apparently there is a query parameter ref can be passed to the url
The name of the commit/branch/tag. Default: the repository’s default branch (usually master)

Create environment for repository using gh

Is it possible to create a new environment for a repository https://github.com/org/repo/settings/environments using the gh cli?
The only mention of environment I can find in the manual is here https://cli.github.com/manual/gh_secret_set where it says you can assign a secret to an existing environment, but it seems the environment would have to be created manually.
From what I'm seeing here in the gh cli repo that's going to be a no at this time. The issue [linked] is an enhancement request for just that.
I too wanted to know if this could be done, as it's part of my workflow to inject environment secrets.
You can still use the API to create it though.
curl -X PUT \
-H 'Authorization: Bearer ghp_...' \
-H 'Accept: application/vnd.github.v3+json' \
https://api.github.com/repos/<org>/<repo>/environments/<env>
Basically you need to create the environment first, then you can set branch policies:
jq -n '{"deployment_branch_policy": {"protected_branches": false, "custom_branch_policies": true}}'|gh api -H "Accept: application/vnd.github+json" -X PUT /repos/:owner/:repo/environments/dev --input -
gh api --method POST -H "Accept: application/vnd.github+json" "/repos/Oceaneering/it_infra_base_application_bootstrapper/environments/dev/deployment-branch-policies" -f name=dev
I wrote a python script for my use case that uses the gh cli to create environments and can include a branch pattern.

Github Workflow - Remove label at the end?

I have a workflow that is triggered when the pull request is labeled (via pull_request_target).
I would to automatically remove the label that triggered the analysis as the last step of that workflow.
How can I do that?
On Github: every pull request is an issue (but not every issue is a pull request).
You can find more informations about this on this stackoverflow answer.
Therefore, you could use the Github API to remove a (specific) label from an issue (or an action doing the same thing) as the last step of your workflow, using the PR number.
Here is the API on Github to remove label from issue (Official Documentation)
If you want to call it directly from the shell in your workflow with curl, it will looks like this:
curl \
-X DELETE \
-H "Accept: application/vnd.github.v3+json" \
https://api.github.com/repos/<owner>/<repo>/issues/<pr_number>/labels/<label_name>
GuiFalourd does indeed have the correct answer, but I did have to improve on it a bit.
If you want to use the workflow on a private repo, you do need to add an authorization token. Here's an example that uses GitHub context to populate everything besides the label name you want to delete:
curl --silent --fail-with-body \
-X DELETE \
-H 'Accept: application/vnd.github.v3+json' \
-H 'Authorization: token ${{ github.token }}' \
'https://api.github.com/repos/${{ github.repository }}/issues/${{ github.event.number }}/labels/YOUR-LABEL'
Also if your label has spaces, use %20 for the whitespace.

How to create a pull request after authentication using Github Enterprise API?

I have written a shell script to create a pull request with Github Enterprise API.
#!/bin/sh
CURRENT_BRANCH=$(git branch --show-current)
git stash save
git checkout master
git pull
UUID=$(uuidgen)
git checkout -b "${UUID}"
npm version patch
git add package.json
git commit -m "#; update version script test"
git push origin "${UUID}"
curl -u [MY_USER_NAME]:[MY_TOKEN] https://github.[MY_ORGANIZATION].com/api/v3/user
curl \
-X POST \
-H "Accept: application/vnd.github.v3+json" \
https://github.[MY_ORGANIZATION].com/api/v3/repos/Modules/[MY_REPO]/pulls \
-d "{'head':'${UUID}','base':'master'}"
The log is displayed as below.
It fail to create the pull request with the error
"message": "Must authenticate to access this API."
However, there seems no issue with the authentication.
// omit some useless log here
remote:
To github.microstrategy.com:Modules/mstr-web-hierarchy.git
* [new branch] 23CFA0E3-33D1-489E-9E55-D38F92BB1B99 -> 23CFA0E3-33D1-489E-9E55-D38F92BB1B99
{
"login": "shizhang",
"id": 1191,
// some useless properties here
{
"message": "Must authenticate to access this API.",
"documentation_url": "https://docs.github.com/enterprise/3.0/rest"
}
Your second curl does not seem to include any authentication information.
Try adding the same -u [MY_USER_NAME]:[MY_TOKEN] as you used in the first curl.
In other words, the first curl success does not mean other curls would benefit from an authenticated session.
Problems parsing JSON
Try with a simpler JSON, just for testing.
And pay attention to quotes: '${UUID}' would not be expanded, and would remain exactly as '${UUID}'.

How do you create a project in a specific group via GitLab API?

I tried to use GitLab API to create a new project. This worked, but this is in my user space:
curl \
--header "Authorization: Bearer ${GITLAB_API_TOKEN}" \
--request POST \
"https://gitlab.com/api/v4/projects/?name=$test-proj"
But I wanted to do it under a specific group with group_id <group_id> (I blanked it here). The most sensible approach that occured to me was:
curl \
--header "Authorization: Bearer ${GITLAB_API_TOKEN}" \
--request POST \
"https://gitlab.com/api/v4/groups/<group_id>/projects/?name=test-proj
But this did not work. Are there any suggestions on how I could achieve this?
I consulted the following references
https://forum.gitlab.com/t/create-a-new-project-in-a-group-using-api/1552
https://docs.gitlab.com/ee/api/projects.html#create-project
The GitLab documentation mentions the path or namespace_id attribute (although I would actually be in search of a group_id attribute). I am not sure about path and how to specify that. I tried - without success - to retrieve the namespace_id via
curl --header "PRIVATE-TOKEN: ${GITLAB_API_TOKEN}" "https://gitlab.example.com/api/v4/namespaces"
It is well possible that I might not have the rights to do the required operation. Therefore a reference to an official (GitLab) documentation together with a test curl command that works would be very helpful to me - thank you!
For anyone looking for the direct command:
STEP 1:
Navigate as below and identify the group ID from GUI:
Admin Area -> Groups -> GroupName
STEP 2:
Construct the command with two parameters viz., name, namespace_id
curl --header "PRIVATE-TOKEN: <myprivatetoken>" -X POST "https://gitlab.com/api/v4/projects?name=myexpectedrepo&namespace_id=38"
Both users and groups are considered "namespaces" as far as the Gitlab API is concerned, so you can use either a group ID or a username in the namespace_id field. You can see this in use by getting a single namespace with either a Group ID (that you can see in the /groups API call, or from a Group's "profile" page) or a username:
# this will show the namespace details of the Group with ID 54
curl --header "PRIVATE-TOKEN: ${TOKEN}" "https://gitlab.com/api/v4/namespaces/54
# this will show the namespace details of the User with username my-username
curl --header "PRIVATE-TOKEN: ${TOKEN}" "https://gitlab.com/api/v4/namespace/my-username
If you have the appropriate access level, you can assign a git remote to your local repository that includes your group name. Then, the push event will trigger GitLab to create the remote repository.
$ mkdir project_name && cd $_
$ echo "# project_name" > README.md
$ git init; git add .; git commit -m initial
$ GITLAB_HOST="gitlab.com"
$ git remote add origin git#${GITLAB_HOST}:group_name/project_name.git
$ git push origin HEAD
Then, point your browser to ${GITLAB_HOST}/group_name/project_name

Post a comment on Github Pull Request via Command Line

Is there a way I can post a comment on a Github Pull Request via the command line? The ideas is that I want Jenkins to post comments on Pull Requests with a summary of the results of a script.
This is absolutely possible with nothing more than curl.
curl \
-X POST \
-H "Accept: application/vnd.github.v3+json" \
-H "Authorization: Bearer $GITHUB_TOKEN" \
https://api.github.com/repos/octocat/hello-world/issues/42/comments \
-d '{"body":"Hello Github!"}'
Read more about the API in use here https://docs.github.com/en/rest/reference/issues#create-an-issue-comment
NOTE: This assumes you have a Personal Access Token stored in an environment variable named GITHUB_TOKEN
It's not possible without third party extensions.

Sorry I can't help more!
This is a little late, but this sounds like exactly what you are looking for:
gh pr comment 6 --body "Hi from GitHub CLI"
https://cli.github.com/manual/gh_pr_comment
Simply allows you to add comments to a pr from a given pr number.
