MIB (Manager image builder)

mib build multiple images with dependencies with other images.

A multi-build is detect by change of a commit.

mib generate also a document with data specified in each directory.

Use case

mib is very useful when you store all you Dockerfile in the same folder like this :

.
├── debian
│   └── v1
│       │── Dockerfile
│       └── bin
├── apline
│   └── v1
│       │── Dockerfile
│       └── config/
│── debian-nginx
│   └── v1
│       │── Dockerfile
│       └── config/
└── debian-nginx-php
    └── v1
        │── Dockerfile      
        └── php/
Or
.
├── debian
│   │── Dockerfile
│   └── bin
├── apline
│   │── Dockerfile
│   └── config/
│── debian-nginx
│   │── Dockerfile
│   └── config/
└── debian-nginx-php
    │── Dockerfile      
    └── php/

mib will help you to build image in the good order for build first the image parent and after children. For example, if the image debian is parent of debian-ngix and debian-nginx is parent of debian-nginx-php, mib will build all images in this order :

1. `debian`
2. `debian-ngix`
3. `debian-nginx-php`

mib works with two modes :

• build dirty : get all files modified in repository (like git status), and will exclude ".md" and ".txt" extensions file and determine dependency between image
• build commit [commit sha] : get all files modified in commit change in repository, and will exclude ".md" and ".txt" extensions file and determine dependency between image

You can also generate README.md per all images to describe image like this :

# Image : alexandreh2ag/mib:v1.0.0

## Parents
- [alexandreh2ag/alpine:v1.0.0](../../alpine/v1.0.0/README.md)
- [alpine:3.9](https://hub.docker.com/_/alpine)

## Children
- [alexandreh2ag/mib:v1.0.0-dev](../../mib/v1.0.0-dev/README.md)

## Env Var
| Var Name | Value |
| -------- | ----- |
| GID  | Host group id (id -g)  |
| UID  | Host user id (id -u)  |

## Packages
| Var Name | Value |
| -------- | ----- |
| ca-certificates  |
| curl  |   |
| vim  |   |
| wget  |   |

## Alias
- foo/alpine:v1.0.0

File generated by mib v1.1.0 / February 07, 2019 12:44:17

This file will be generate with data your set in mib.yml. This file is also used for build image. So, if you want use mib you must add this file for all of your images like this :

.
├── debian
│   └── v1
│       │── Dockerfile
│       │── mib.yml
│       └── bin
├── apline
│   └── v1
│       │── Dockerfile
│       │── mib.yml
│       └── config/
│── debian-nginx
│   └── v1
│       │── Dockerfile
│       │── mib.yml
│       └── config/
└── debian-nginx-php
    └── v1
        │── Dockerfile
        │── mib.yml   
        └── php/

Global configuration (optional)

mib can be configured to set log level or change default template used for README.md image. For configure mib add config.yml at the root of dir.

Currently, you can configure this parameters :

build:
    extensionExclude: ".md,.txt" #default extension files that will be exclude when run `build` or `generate`
template:
    imagePath: "my-custom-image.tmpl" # Define a custom template for image
    indexPath: "my-custom-index.tmpl" # Define a custom template for index

  mib [command]

Available Commands:
  build       build sub commands
    commit      Build image for specific commit
    dirty       Build image with change not committed
  commit      Commit all changes
  completion  Generate the autocompletion script for the specified shell

  version     Show version info

Flags:
  -c, --config string   Define config path
  -w, --dir string      Define working dir (default "/home/alexandre/projects/labs/mib")
  -h, --help            help for mib
  -l, --level string    Define log level (default "INFO")

Requirements

• Docker (26.0+)
• Git (2.25+)

Packages

sudo apt install -y qemu-user-static binfmt-support

Docker multiple platform

For build an image for a different platform or multiples platform you must enable feature containerd-snapshotter.

Development

• Generate mock:

  ./bin/mock.sh

• Build the project:

  go build .

• Run tests:

  go test ./...

Production

• Run mib with docker:

  docker run -it -v /var/run/docker.sock:/var/run/docker.sock -v ${PWD}:/build alexandreh2ag/mib:${VERSION} mib --help

• Install binary to custom location:

  curl -L "https://github.com/alexandreh2ag/mib/releases/download/${VERSION}/mib_$(uname -s)_$(uname -m)" -o ${DESTINATION}/mib
  chmod +x ${DESTINATION}/mib
