How do I clone a GitHub wiki?

Any GitHub wiki can be cloned by appending wiki.git to the repo url, so the clone url for the repo https://myorg/myrepo/ is: [email protected]:myorg/myrepo.wiki.git (for ssh) or https://github.com/my/myrepo.wiki.git (for https).

You make edits, and commit and push your changes, like any normal repo. This wiki repo is distinct from any clone of the project repo (the repo without wiki.get appended).

How do I add images to a wiki page?

You've been working locally for awhile. You're ready to push some changes, but someone else pushed something! You have to pull in their changes before you can push yours.

git pull origin master forces you to create a merge commit, which is annoying.

Instead, do git pull --rebase origin master. This will effectively:

Stash your changes
Pull in the changes from origin
Apply your changes on top

No merge commit!

Transparent proxy for Docker containers

If the Docker host is placed inside a proxy server, it needs to add the proxy configuration to each Dockerfile such as ENV http_proxy.

Following allows transparent access from the container to outside without any proxy configuration.

Set up the transparent proxy
Apply iptables rule for the transparent proxy
