GitLab: Clone all repos from a group​

Install the glab cli tool first.

GITLAB_HOST=gitlab.example.com glab repo clone --group MyGroup --archived=false --preserve-namespace --paginate

Docker: "bash" into a docker container​

I often need to inspect docker images. The following is the command to do this and a break down of the options.

docker run -it --rm IMAGE_NAME /bin/bash

-i, --interactive Keep STDIN open even if not attached -t, --tty Allocate a pseudo-TTY --rm Automatically remove the container when it exits

GitLab CI: Split long commands... there's a bug​

At time of writing (29 Nov 2022) GitLab CI has an embarrassing bug. Certain script failures are not reported. Failures in script files are also not reported unless it's the last command in the script.

If multiple commands are combined into one command string, only the last command’s failure or success is reported. Failures from earlier commands are ignored due to a bug. To work around this, run each command as a separate script item, or add an exit 1 command to each command string.

JavaScript thread sleep​

async function sleep(ms) {
  await new Promise(resolve =>
    setTimeout(resolve, ms)
  )
}

Ruby Gems: execute specific version from several installed​

Multiple versions of a Ruby Gem can be installed for use from the command line. For example to see which versions of bundler you have 

gem list bundler

To use the version you want put the version number between underscores right after the gem command line name (note this may be different than the gem name).

bundle _2.3.4_ install

Node: get package.json version​

$ node -p "require('./package.json').version"

Git: Step through commits on a branch​

Walk through commits on a branch by jumping back a number of commits from the branch head.

git checkout <branch-name>~<number>
git checkout spam_and_eggs~5
git checkout spam_and_eggs~6

Git SSH for multiple remote servers​

~/.ssh/config:

Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/personal_github

Host github.company.com
  HostName github.company.com
  User git
  IdentityFile ~/.ssh/work_github

K8S: How to print Opaque Secrets​

kubectl get secret <SECRET_NAME> -o jsonpath="{.data.<DATA>}" | base64 --decode

GitHub: Find repos you own in an Organization​

It is impossible on the GitHub website to see a list of repos in an Organization that you own.

Here is a GraphQL query (with query variables) that gets you pretty close. You still have to manually filter repos forked from an Organization repo. The login values in the response can help select the org you care about. You can run the query on https://docs.github.com/en/graphql/overview/explorer. Don't forget to sign in.

query pagination($first: Int!, $after: String = null) {
    viewer {
        repositories(first: $first, after: $after, affiliations: [ORGANIZATION_MEMBER]) {
            totalCount
            nodes {
                name, url
                owner { login }
            }
            pageInfo {
                startCursor, endCursor
                hasPreviousPage, hasNextPage
            }
        }
    }
}

Here is the REST api version: 

curl \
  -H "Accept: application/vnd.github.v3+json" \
  -u "$USERNAME:$PERSONAL_ACCESS_TOKEN" \
  https://api.github.com/user/repos?affiliation=organization_member&per_page=100&page=1
