Shell script builds Docker semi-automatic compilation, packaging and release application operations

Shell script builds Docker semi-automatic compilation, packaging and release application operations

The Docker publishing method provides many conveniences for implementing DevOps (automated operation and maintenance, which requires configuring code management tools such as Git hooks to implement a series of event controls such as submission, compilation, packaging, and release), and can be well coordinated with Shell scripts.

Docker images can be obtained through automatic compilation or by importing images.

The title of this article is: Shell script builds Docker for semi-automatic compilation, packaging and release, because I haven’t yet associated it with code management.

Shell script different implementations

Import image method (image file rtvsweb-publish.tar):

Build and release method (built by Dockerfile):

Shell Docker build release script tool core install.sh

Overall design implementation ideas

1. Docker environment preparation and installation

2. MySQL environment preparation and installation

3. Docker knowledge: build and run

4. Version management of Docker images

5. Network access during tolerance: --link

6. Image packaging history

7. Service operation effect

The above is my personal experience. I hope it can give you a reference. I also hope that you will support 123WORDPRESS.COM. If there are any mistakes or incomplete considerations, please feel free to correct me.
