my kubernetes eco system local demo

Requirements:

• macOS
• brew ( https://brew.sh/ )
• ansible (brew install ansible )
• minikube ( brew cask install minikube )
• kubectl ( brew install kubernetes-cli ) (when you install the current version it will not work as the kubectl v1.8.0 does not work with kubernetes v.1.7.5, brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/1e866e9cd915c37184c248fb726775ff8a30c91e/Formula/kubernetes-cli.rb does work)
• dnsmasq ( brew install dnsmasq )
• in your sudoers file: username ALL=NOPASSWD: /usr/local/bin/brew services restart dnsmasq
• probably more... when you find it, please create an issue
• RAM, lots of it ;-) (default setting is now 8192MB for the VM)

How to run

ansible-playbook setup.yaml

coffee! it takes a while (especially on slow internet connections) on my 2015 mbp with 150MBit it takes about 10 minutes

to clean it up: minikube delete want to access the docker deamon inside:

eval $(minikube docker-env) && docker ps

urls after running:

• http://dashboard.example.com
• http://jenkins.example.com
• http://gitlab.example.com
• http://prometheus.example.com
• http://alerts.example.com

( it is really example.com, you can change it in inventory/group_vars/all.yaml )

Todo:

• On Jenkins start build the a new jenkins slave image, containing klar and maybe other binaries
• coreos/clair
• migrate to official gitlab helm charts
• spotify gc
• BELK/EFK
• LDAP
• keycloak or dex (maybeish)
• calico/canal when this can actually work in minikube

Preflight solutions

Resolver settings

mkdir -p /etc/resolver
echo "nameserver 127.0.0.1 > /etc/resolver/example.com

install dnsmasq

brew install dnsmasq

install minikube

brew cask install minikube

Current issues

• Jenkins doesnt really autostart first build (only after you set containers +1 and save)
• registry ingress controller is acting weired, need to delete and create
