ANSIBLE CONTAINER PROVIDES AN ANSIBLE-CENTRIC WORKFLOW FOR BUILDING, RUNNING, TESTING, AND DEPLOYING CONTAINERS

APPLY THE POWER OF ANSIBLE AND REUSE YOUR EXISTING ANSIBLE CONTENT FOR YOUR CONTAINERIZED ECOSYSTEM.

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

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

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

SCOPE ● Definition (instead of Dockerfile) ● Build (instead of docker build) ● Run (instead of docker-compose run) ● Deploy (to cloud env)

Define deploy build container.yml CONTAINER DEFINITION run (dev) (prod)

EARLY REACTIONS ● Many exceptions, not meaningful tracebacks ● Build process is still fragile ● Layering roles to build images is cool
