### Purpose
As more and more packages are made into docker images, keeping them up to date become a tedious task.
Some images just pull package without specifying version and update means rebuilding them blindly. And there is no version info from image tag.
Auto_Docker intend to ease this burden, at least for simple docker images that depends on single package. It can update Dockerfile, README.md, apply git commit and tag according to new version.
### Features
- [x] Update project
- [x] Dockerfile
- [x] README.md
- [x] LICENSE
- [x] Dry run
- [x] Try build
- [x] Update DB
- [x] Alpine
- [x] Auto git commit
- [x] Auto git tag
A framework for automatically updating simple docker project.
### Usage
```sh
git clone https://github.com/J-Siu/auto_docker.git
cd auto_docker
```
```txt
./auto_docker
Usage:
./auto_docker [flags]
Flags:
-commit Apply git commit. Only work with -save
-tag Apply git tag. Only work with -commit
-debug Show debug log
-h, -help Show help
-nobuild Do not perform docker build
-noskip Do not skip project
-pref, -prefix string Path prefix for project
-proj, -project string Path of project
-save Write back to project folder
-updatedb Update package database
```
Example directory tree:
```sh
.
├── auto_docker
├── docker_amule
├── docker_compose
├── docker_dnsmasq
├── docker_hostapd
├── docker_hugo
├── docker_mldonkey
├── docker_mpd
├── docker_mpd_lite
├── docker_postfix
├── docker_testing
├── docker_tor
├── docker_transmission
└── docker_unbound
```
Update db:
```sh
cd auto_docker
./auto_docker -debug -updatedb
```
Process 1 docker project `docker_amule`:
Test run only ...
```sh
cd auto_docker
./auto_docker -debug -project ../docker_amule
```
Save ...
```sh
cd auto_docker
./auto_docker -debug -project ../docker_amule -save
```
Git commit too ...
```sh
cd auto_docker
./auto_docker -debug -project ../docker_amule -save -commit
```
Process all docker projects `docker_`, use `-prefix`:
Test run only ...
```sh
cd auto_docker
./auto_docker -debug -prefix ../docker_
```
Use `-project` to specify single project
Use `prefix` to specify projects with common path prefix
Multiple `-project` and `-prefix` can be used together.
### Workflow
#### Generate DB
```sh
cd auto_docker
./auto_docker -debug -updatedb
```
When `-updatedb` is used. All `${auto_distro_root}//${auto_db_script}` will be executed. Each will generate a `${auto_data_root}/db//${auto_db_data}`.
With default configuration, related file structure as follow:
```sh
./ (${auto_root})
├── data/ (${auto_data})
│ └── db/
│ ├── alpine/ ()
│ │ ├── edge/ (download dir used by db.sh)
│ │ ├── latest-stable/ (download dir used by db.sh)
│ │ └── db.data (${auto_db_data})
│ └── debian/ ()
│ └── db.data (${auto_db_data})
├── distro/ (${auto_distro_root})
│ ├── alpine/ ()
│ │ ├── db.sh (${auto_db_script})
│ │ └── distro.conf (${auto_db_conf})
│ └── debian/ ()
│ ├── db.sh (${auto_db_script})
│ └── distro.conf (${auto_db_conf})
├── auto.common.sh
├── auto.conf
└── auto_docker
```
> Distro `debian` script is not available now.
#### Staging
A docker project is being copied under staging area ${auto_stg_root} before being process. All changes will be applied there.
```sh
cd auto_docker
./auto_docker -debug -prefix ../docker_
```
Projects are copied into `${auto_stg_root}`:
```sh
data/ (${auto_data})
└── stg/ (${auto_stg_root})
├── docker_amule
│ ├── docker-compose.yml
│ ├── Dockerfile
│ ├── env
│ ├── LICENSE
│ ├── README.md
│ └── start.sh
├── docker_dnsmasq
│ ├── docker-compose.yml
│ ├── Dockerfile
│ ├── env
│ ├── LICENSE
│ └── README.md
├── docker_hostapd
│ ├── docker-compose.yml
│ ├── Dockerfile
│ ├── env
│ ├── LICENSE
│ └── README.md
└── docker_hugo
├── Dockerfile
├── LICENSE
├── README.md
└── start.sh
```
If new package version is found, `Dockerfile` will be updated and a testing `docker build` will be performed.
`docker build` test can be skipped with `-nobuild`.
> As long as `-save` is not used, nothing will change in the original project folder. It is advice to inspect the staging files before using the `-save` option.
#### Save
`-save` option will copy `Dockerfile`, `LICENSE` and `README.md` back to original project folder.
#### Commit
`-commit` will commit with new package version. Only has effect with `-save`.
```sh
git commit -a -m ${dockerfile["version"]}
```
#### Tag
`-tag` will tag with new package version. Only has effect with `-commit`.
```sh
git tag -a ${dockerfile["version"]} -m ${dockerfile["version"]}
```
### What Is Being Updated
#### Dockerfile
Take following `Dockerfile` as example:
```sh
FROM alpine:edge
LABEL version="0.73.0-r0"
LABEL maintainers="[John Sing Dao Siu](https://github.com/J-Siu)"
LABEL name="hugo"
LABEL usage="https://github.com/J-Siu/docker_hugo/blob/master/README.md"
RUN apk --no-cache add git hugo=0.73.0-r0
...
```
Package name is taken from `name` label.
Package version is taken from `version` label.
They are then compare with distro db. If new version is found, the version will be update accordingly, including version line 8.
`maintainer` and `usage` will also be updated if they are available.
#### README.md
Take following `README.md` as example:
```md
- 0.73.0-r0
- something ...
```
If version is updated to `0.74.0`, new lines will be automatically added before `` as follow:
```md
- 0.73.0-r0
- something ...
- 0.74.0
- Auto update to 0.74.0
```
If there copyright line as follow:
```txt
Copyright (c) xxxx
```
It will be updated with current year:
```txt
Copyright (c) 2020
```
#### License
`LICENSE` file, if there copyright line as follow:
```txt
Copyright (c) xxxx
```
It will be updated with current year:
```txt
Copyright (c) 2020
```
### Limitation
- Distro
- Only alpine:latest and alpine:edge are supported now.
- Dockerfile
- `name` label must be same as package name.
- `version` label must be same as package version.
### Distro and DB
The `${auto_distro_root}/` directory provide a way to extend support for more distro.
#### db.sh ${auto_db_script}
`db.sh` of each distro should start with following:
```sh
#!/bin/bash
# --- db.sh common start ---
COMMON="auto.common.sh"
source ${COMMON}
common_option ${@}
_my_path=${BASH_SOURCE[0]}
_my_name=$(basename ${_my_path})
_my_dir=${_my_path/%\/${_my_name}/}
source ${_my_dir}/${auto_db_conf}
_db_path=${auto_db_root}/${my_distro_name}/${auto_db_data}
# --- db.sh common end ---
```
`db.sh` only task is to produce `db.data` at `${_db_path}`.
#### distro.conf
```sh
# --- distro.conf common start ---
tags="latest edge" # latest / edge
# --- distro.conf common start ---
```
#### db.data ${auto_db_data}
`db.sh` create `db.data` in following format:
```sh
::
::
::
...
```
Example:
```sh
latest::geoclue-dev
2.5.6-r1
latest::vdr
2.4.1-r0
latest::krfb-lang
20.04.2-r0
```
