3. Recap - Day ONE - setup a VM on DigitalOcean - install Chef Server - install Docker - pull ubuntu Docker image - create a container
4. Agenda - Day TWO - learn how to create docker containers and bootstrap them using chef https://gist.github.com/pungoyal/7464366
5. Every Chef needs a ---
7. Configure Knife # install chef client package $ curl -L https://www.opscode.com/chef/install.sh | sudo bash # get docker gateway address $ ifconfig docker0 | grep inet # USE the address e.g. https://172.17.42.1:443 from above $ knife configure --initial # check setup $ knife client list
8. Install Berkshelf # add ruby to path $ echo "export PATH=\$PATH:/opt/chef/embedded/bin" >> ~/.bashrc $ source ~/.bashrc && ruby -v # get dev tools $ aptitude install build-essential zlib1g-dev git libssl-dev openssl libreadline-dev libxslt-dev libxml2-dev -y # install berkshelf $ gem install berkshelf --no-ri --no-rdoc $ berks init workshop $ mkdir -p ~/.berkshelf $ echo "{\"ssl\": {\"verify\": false}}" > ~/.berkshelf/config.json # turn off ssl for the time being
9. Create docker containers $ docker run -p 22 -d pungoyal/ubuntu:sshd $ docker ps $ ssh localhost -l root -p <port>
10. chef-repo $ git clone https://github.com/opscode/chef-repo.git $ echo "site :opscode" > Berksfile # add 'ntop' and 'htop' cookbooks in Berksfile $ berks install $ berks upload
11. fix chef-server config $ chef-server-ctl reconfigure
