This project come with a structure to facilitate further images (like pluie/alpine-apache & pluie/alpine-mysql)
|
||
|
|
|
||
|
|
## Docker image size
|
||
|
|
|
||
|
|
- very small image < 10 MB
|
||
|
|
|
||
|
|
|
||
|
|
## Docker image usage
|
||
|
|
|
||
|
|
```
|
||
|
|
$ docker run --name alpine pluie/alpine
|
||
|
|
```
|
||
|
|
|
||
|
|
## Docker image structure
|
||
|
|
|
||
|
|
```
|
||
|
|
project/
|
||
|
|
|
|
||
|
|
|-- install.d/ # deployed in /scripts on target container
|
||
|
|
| | # launch on docker image building process
|
||
|
|
| | # XX-name.sh - low XX are run first
|
||
|
|
| |-- 00-util.sh
|
||
|
|
| |-- 40-fix.sh
|
||
|
|
|
|
||
|
|
|-- pre-init.d/ # deployed in /scripts on target container
|
||
|
|
| | # launch on docker container running process
|
||
|
|
| |-- 50-example.sh
|
||
|
|
|
|
||
|
|
|-- build # build docker image : ./build [TAG]
|
||
|
|
|-- common.sh # don't modify - sourced by main.sh to execute pre-init.d scripts first
|
||
|
|
|-- install.sh # don't modify - execute install.d scripts on docker building process
|
||
|
|
|-- main.sh # source common.sh then execute entry point instruction
|
||
|
|
|-- util.sh # sourced by common.sh
|
||
|
|
```
|
||
|
|
|
||
|
|
you can easily create your own images based on this structure.
|
||
|
|
keep an eye to pluie/alpine-apache & pluie/alpine-mysql wich extend pluie/alpine
|
||
|
|
|
||
|
|
|
||
|
|
## Extend pluie/alpine Image
|
||
|
|
|
||
|
|
RUN instructions are minimized
|
||
|
|
on extended image you can only use :
|
||
|
|
```
|
||
|
|
RUN bash /scripts/install.sh
|
||
|
|
```
|
||
|
|
add your packages in a script in install.d directory
|
||
|
|
keep name below 40 because install.d/40-fix.sh clean package repository
|
||
|
|
each extended image inherit install.d && pre-init.d scripts
|
||
|
|
|
||
|
|
UNIQ ENTRYPOINT - extended images doesn't need to define ENTRYPOINT
|
||
|
|
you can keep intact build script in each extended project
|
||
|
|
manage your install & init instruction in install.d & pre-init.d directory
|
||
|
|
and write your own main.sh script
