Chapter 4. Docker Migration Guide
If you want to integrate Docker into your enterprise but you’re not sure how to get started, this chapter is for you. It discusses the decisions you’ll have to make as you plan a migration to Docker containers, resources that can help smooth the process, and potential pitfalls to avoid.
Planning Your Migration
The first step in migrating to Docker containers is to identify how you want to use them. This is important because, as earlier chapters have noted, Docker containers will exist alongside virtual machines or other older forms of infrastructure technology. A successful Docker strategy requires evaluation of which types of workloads you want to migrate to containers, and where your containers will fit within the rest of your infrastructure.
Questions to ask yourself as you plan a Docker migration include:
- Will you use Docker for application deployment in production environments or just for development? Docker can help your developers streamline their work by making application testing and updates easier. It can also make end-user applications more flexible and scalable, but it does not have to be used in production.
- Will you migrate legacy applications to Docker, or only deploy new applications inside containers?
