There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.

All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.

1. Loop variables are scoped outside the loop.

What do these lines do? Make predictions and then scroll down.

func print(pi *int) { fmt.Println(*pi) }

IL that git push -u origin my-new-branch  is no more needed with push.autoSetupRemote :
git config --global --add --bool push.autoSetupRemote true

git config --global --add --bool pull.rebase true
git config --global --add --bool rebase.autoStash true
git config --global --add --bool fetch.prune true
# git undo
git config --global alias.undo '!f() { \

MicroService Proxy Gateway Solutions

Kong, Traefik, Caddy, Linkerd, Fabio, Vulcand, and Netflix Zuul seem to be the most common in microservice proxy/gateway solutions. Kubernetes Ingress is often a simple Ngnix, which is difficult to separate the popularity from other things.

Originally, I had included some other solution

Creating the cluster

You should create a Vagrantfile in an empty directory with the following content:

Setup multiple git identities & git user informations

/!\ Be very carrefull in your setup : any misconfiguration make all the git config to fail silently ! Go trought this guide step by step and it should be fine 😉

Setup multiple git ssh identities for git

• Generate your SSH keys as per your git provider documentation.
• Add each public SSH keys to your git providers acounts.
• In your ~/.ssh/config, set each ssh key for each repository as in this exemple:
