> `kiwi` - simple, consistent, powerful
|
|
|
|
The simple tool for managing container servers
|
|
|
|
|
|
## Quick start
|
|
|
|
- Learn to use `docker` with `docker-compose`
|
|
- Install kiwi-scp
|
|
- Look at [the example instance](./example)
|
|
- Look at the output of `kiwi --help`
|
|
- Start building your own instances
|
|
|
|
|
|
## Installation
|
|
|
|
A convenience installer is available as [install.sh](./install.sh) in this directory.
|
|
You can `curl | sh` it using the following one-liner.
|
|
|
|
```shell script
|
|
curl --proto '=https' --tlsv1.2 -sSf 'https://raw.githubusercontent.com/ldericher/kiwi-scp/master/install.sh' | sh
|
|
```
|
|
|
|
The installer downloads the `kiwi` launcher script and installs it to a location of your choice.
|
|
Please consider installing into a directory inside your `$PATH`.
|
|
Run in a root shell or use `sudo sh` instead for system-wide installation.
|
|
|
|
You should now be able to run `kiwi init --show` and see the default configuration file.
|
|
This downloads the latest version of the main kiwi-scp executable and sets it up for you.
|
|
|
|
|
|
### Adjusting environment for `kiwi`
|
|
|
|
The `kiwi` executable depends on [Python](https://www.python.org/) 3.6 (or later), [pipenv](https://pipenv.pypa.io/), and
|
|
[less](http://www.greenwoodsoftware.com/less/) being in your `$PATH`.
|
|
|
|
In some cases, notably when using a multi-version system such as
|
|
[CentOS SCL](https://wiki.centos.org/AdditionalResources/Repositories/SCL), not all of these are in your `$PATH`
|
|
at login time.
|
|
|
|
In those cases, you can simply create a `.kiwi_profile` file in your home directory.
|
|
It will be sourced every time you use the `kiwi` command.
|
|
For the aforementioned case where you installed `centos-release-scl` and `rh-python36`, your `~/.kiwi_profile` should
|
|
contain:
|
|
|
|
```shell script
|
|
#!/bin/sh
|
|
|
|
. /opt/rh/rh-python36/enable
|
|
```
|
|
|
|
|
|
## Get started
|
|
|
|
### Create a kiwi-scp instance
|
|
|
|
Any directory is implicitly a valid kiwi-scp instance using the default configuration.
|
|
To prevent surprises however, you should run `kiwi init` in an empty directory and follow its directions to
|
|
create a `kiwi.yml` before using `kiwi` more.
|
|
|
|
|
|
### Concept
|
|
|
|
A kiwi-scp instance is a directory containing a bunch of static configuration files.
|
|
"Static" there as in "those don't change during normal service operation".
|
|
These files could be anything from actual `.conf` files to entire html-web-roots.
|
|
|
|
Non-static, but persistent files are to be kept in a "service data directory", by default `/var/kiwi`.
|
|
In your `docker-compose.yml` files, you can refer to that directory as **${TARGETROOT}**.
|
|
|
|
Start the current directory as a kiwi-scp instance using `kiwi up`, or stop it using `kiwi down`.
|
|
This also creates kiwi's internal hub network, which you can use as **kiwi_hub** in your `docker-compose.yml` files.
|
|
|
|
|
|
### Projects
|
|
|
|
A kiwi-scp instance usually contains several projects.
|
|
A project is a collection of dependent or at least logically connected services, described by a `docker-compose.yml`.
|
|
A well-known example would be webserver + php + database.
|
|
|
|
To create a project, use the `kiwi new <project-name>` command.
|
|
By default, this creates a new disabled project.
|
|
Before enabling or starting, consider editing the new project's `docker-compose.yml` file to your liking.
|
|
Finally, enable it with `kiwi enable <project-name>`.
|
|
You can also create, enable or (analogously) disable multiple projects in a single command.
|
|
|
|
Each project will have its own place in the service data directory, which you can refer to as **${TARGETDIR}**.
|
|
|
|
Finally, start a project using `kiwi up <project-name>`.
|
|
|
|
|
|
### Advanced kiwi usage
|
|
|
|
kiwi-scp extends the logical bounds of `docker-compose` to handling multiple projects.
|
|
|
|
|
|
#### The `kiwi_hub`
|
|
|
|
With kiwi-scp, you get the internal kiwi_hub network for free.
|
|
It allows for network communication between services in different projects.
|
|
Be aware, services only connected to the kiwi_hub can't use a port mapping!
|
|
In most cases, you will want to use this:
|
|
|
|
```yaml
|
|
networks:
|
|
- default
|
|
- kiwi_hub
|
|
```
|
|
|
|
|
|
#### The `CONFDIR`
|
|
|
|
Sometimes, it's convenient to re-use configuration files across projects.
|
|
For this use case, create a directory named `conf` in a project.
|
|
Those will all be combined into a directory available as **${CONFDIR}** in your `docker-compose.yml` files.
|
|
|
|
|
|
#### `kiwi.yml` options
|
|
|
|
##### `version`
|
|
Version of kiwi-scp to use for this instance.
|
|
Default: Latest version.
|
|
|
|
##### `runtime:storage`
|
|
Path of the service data directory, available as **${TARGETROOT}** in projects.
|
|
Default: `/var/kiwi`
|
|
|
|
##### `runtime:shells`
|
|
List of additionally preferable shell executables when entering service containers.
|
|
Default: `- /bin/bash`
|
|
Example:
|
|
|
|
```yaml
|
|
runtime:
|
|
shells:
|
|
- /bin/zsh
|
|
- /bin/fish
|
|
```
|
|
|
|
##### `runtime:env`
|
|
Associative array of custom variables available in projects' `docker-compose.yml` files.
|
|
Default: `null`
|
|
Example:
|
|
|
|
```yaml
|
|
runtime:
|
|
env:
|
|
HELLO: "World"
|
|
FOO: "Bar"
|
|
```
|
|
|
|
#### For everything else, look at `kiwi --help`
|
|
#### Happy kiwi-ing!
