We are going to use OWASP ZAP as a container in this chapter, which requires container runtime in the host operating system. The team behind OWASP ZAP releases ZAP Docker images on a weekly basis via Docker Hub. The approach of pulling Docker images based on tags is popular in modern DevOps environments and it makes sense that we talk about automation with respect to that.
Official ZAP is now available with stable and weekly releases via the Docker container at Docker Hub: https://github.com/zaproxy/zaproxy/wiki/Docker.
