nginx config that uses the oauth2-proxy (via auth_request) to authenticate against gitlab and then proxies all requests to a backend service while setting the auth headers X-User and X-Email
server {
listen 80;
server_name localhost;
location /oauth2/ {
proxy_pass http://oauth-proxy:4180;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_set_header X-Auth-Request-Redirect $request_uri;

Using Amazon CNI with kops-created Kubernetes cluster

AWS CNI plugin is now merged with kops: kubernetes/kops#3997. This gist explains how to build kops, create a Kubernetes cluster using correct --networking option, and then test it.

Build kops

export GOPATH=`pwd`
mkdir src/k8s.io; cd src/k8s.io
git clone git@github.com:kubernetes/kops.git
cd kops
export S3_BUCKET_NAME=<some bucket you own>

Automatic version numbers of your git repository using git hooks

Put this in a file called pre-commit in .git/hooks/

#!/bin/sh
# To enable this hook, rename this file to "pre-commit".

git rev-list --count master > build_number

Build a modified CoreOS kernel (no initramfs modules; X260 driver notes)

Download and start the CoreOS development image in a container. Make sure to bind writable directories over the kernel's build and install paths.

wget 'http://alpha.release.core-os.net/amd64-usr/current/coreos_developer_container.bin.bz2'
bzcat coreos_developer_container.bin.bz2 > coreos_developer_container.bin
mkdir boot modules src
sudo systemd-nspawn \
    --bind="$PWD/boot:/boot" \
    --bind="$PWD/modules:/lib/modules" \

--bind="$PWD/src:/usr/src" \

Why I prefer CLI over UI ?

  • CLI tools are Composable using pipes (great old school example http://www.youtube.com/watch?v=tc4ROCJYbm0&t=5m32s)
  • Great for automation and batch processing
  • Fewer mouse clicks. Can go futher using only keyboard
  • Avoid cluky UIs especially over poor connections
  • I'm insulated from UI changes
  • Easier to debug as they are often more verbose than the UI

The DC/OS CLI (https://dcos.io/docs/1.7/usage/cli/)
