An Early Look at Ansible Container

Ansible Container is a tool for building Docker images and orchestrating containers using Ansible playbooks. Learn about building and maintaining your containers using Ansible. End the bash madness of command && command && command (and so on). Enable automation of the entire container build, deployment, and management process. Get an early look at this fast moving project!

1. AN EARLY LOOK AT ANSIBLE CONTAINER END THE BASH MADNESS OF COMMAND && COMMAND && COMMAND. ENABLE AUTOMATION OF THE ENTIRE CONTAINER BUILD, DEPLOYMENT, AND MANAGEMENT PROCESS. Keith Resar @KeithResar
2. @KeithResar Keith Resar: Bio Wear many hats @KeithResar Keith.Resar@RedHat.com Coder Open Source Contributor and Advocate Infrastructure Architect
3. ANSIBLE CONTAINER PROVIDES AN ANSIBLE-CENTRIC WORKFLOW FOR BUILDING, RUNNING, TESTING, AND DEPLOYING CONTAINERS
4. APPLY THE POWER OF ANSIBLE AND REUSE YOUR EXISTING ANSIBLE CONTENT FOR YOUR CONTAINERIZED ECOSYSTEM.
5. FROM node:7.9.0 RUN mkdir -p /app WORKDIR /app ARG NODE_ENV dev ENV NODE_ENV $NODE_ENV COPY package.json /app/ RUN npm install && npm cache clean COPY . /app/ CMD [ "npm", "start" ] DOCKERFILE
6. ANSIBLE CONTAINER’S PROMISE • Build container images and orchestrate them using only Ansible playbooks • Describe your application in a single YAML file • See Ansible roles that make up your container images
7. BUT WAIT, THERE’S MORE Everything Ansible brings to orchestrating your infrastructure can now be applied to the image build process. • Use templates • Copy files • Drop in encrypted data • Handle errors • Add conditionals
8. SCOPE • Definition (instead of Dockerfile) • Build (instead of docker build) • Run (instead of docker-compose run) • Deploy (to cloud env)
9. Define deploy build container.yml CONTAINER DEFINITION run (dev) (prod)
10. postgres django nginx conductor ORCHESTRATING THE BUILD
11. ANSIBLE CONTAINER GREENFIELD
12. ANSIBLE CONTAINER IMPORT FROM DOCKERFILE
13. EARLY REACTIONS • Many exceptions, not meaningful tracebacks • Build process is still fragile • Layering roles to build images is cool
