# prezto docker container
|
|
|
|
This branch contains a Dockerfile and a Makefile that hopefully may
|
|
prove helpful for prezto development.
|
|
|
|
The idea is to have a totally independendn and isolated environemnet
|
|
in which to quickly make changes to either prezto-core or any plugin
|
|
that may bein development, enabling automated testing and even
|
|
continuous integration.

The container is a basic install of alpine linux, so the image
|
|
download is reasonably small
|
|
|
|
On the container we have a few utilities and additionalsoftware that
|
|
prezto has core support for, and you can check it out in a snap by doing:
|
|
|
|
```bash
|
|
docker pull hlecuanda/prezto-dev:latest
|
|
```
|
|
once you have the image, create a container from it with:
|
|
|
|
```bash
|
|
docker run -it --rm -h prezto hlecuanda/prezto-dev:latest
|
|
```
|
|
|
|
That will set you on a prompt within the container with a
|
|
vanilla install of prezto.
|
|
|
|
A development and testing workflow can be achieved by mounting the stuff
|
|
you're working on to the image's filesystem:
|
|
|
|
```bash
|
|
docker run -it --rm -h prezto \
|
|
-v /local/path:/home/prezto \
|
|
-v /local/path/zdotdir:/home/preztoa \
|
|
-v /local/module-dev-src:/home/prezto/.zprezto/modules/yourmodulea \
|
|
hlecuanda/prezto-dev:latest
|
|
```
|
|
|
|
the third volume mapping is particularly interesting. you can
|
|
develop on your own machine and environnment, and when spinning up the
|
|
container, your actual source is already in-plase as if installed on a
|
|
vanilla prezto instance
|
|
|
|
keep in mind that the container are ephemeral, unless you remove the
|
|
`--rm` option which will create new containers each time you run the
|
|
command, but the changes to the filesystemwill persist on a container
|
|
file that you can later spin up again to re-use.
|
|
|
|
I have found epehermeral containers to be most useful since you get an
|
|
untainted, pristine environment for testing every time you spin up the
|
|
container.
|
|
|
|
hope this turns out to be useful.
