Previously we looked at implementing a CI/CD pipeline using both Terraform and Ansible for provisioning and Configuration Management. In this deployment we relied on an official Python Docker image to build our Ansible environment, however this required a few steps that add a few top-heavy steps that could be solved by creating our own Docker image instead. The sample code for this post is in my GitHub here. Speeding up . . .
Previously we’ve discussed the deployment of Docker containers to Azure and managing Scale Out of instances but not the use of Docker directly. The terminology of Docker has become a little confused of late as containers become the new hot topic, for clarity Docker itself is an application that can be used to create, manage and orchestrate containers, and it’s the orchestration that we’re going to be looking at in . . .
