![release prod](https://github.com/DomainDrivenArchitecture/dda-devops-build/workflows/release%20prod/badge.svg)
dda-devops-build integrates all the tools we use to work with clouds & provide some nice functions around.
Tools we support are
* terraform: for setting up the plain infrastructure around.
* docker: for creating images
* c4k: for generating kubernetes manifests
* provs: for setting up small single-node k3s clusters
* gopass: for credential management on devops computers
* cloud providers: hetzner, digitalocean, aws
In addition we provide a ReleaseMixin for release related tasks like tag / publish & version-bump

Principles we follow are:
* Seperate build artefacts from version controlled code
* Domain Driven Design - in order to stay sustainable
## Installation
Ensure that yout python3 version is at least Python 3.10
```
sudo apt install python3-pip
pip3 install -r requirements.txt
export PATH=$PATH:~/.local/bin
```

## Example Build
lets assume the following project structure
```
my-project
| -> my-module
| | -> build.py
| | -> some-terraform.tf
| -> an-other-module
| -> target (here will the build happen)
| | -> ...
```
```python
from pybuilder.core import task, init
from ddadevops import *
name = 'my-project'
MODULE = 'my-module'
PROJECT_ROOT_PATH = '..'
@init
def initialize(project):
project.build_depends_on("ddadevops>=4.0.0-dev")
config = {
"credentials_mapping": [
{
"gopass_path": environ.get("DIGITALOCEAN_TOKEN_KEY_PATH", None),
"name": "do_api_key",
},
{
"gopass_path": environ.get("HETZNER_API_KEY_PATH", None),
"name": "hetzner_api_key",
},
],
"name": name,
"module": MODULE,
"stage": environ["STAGE"],
"project_root_path": PROJECT_ROOT_PATH,
"build_types": ["TERRAFORM"],
"mixin_types": [],
"tf_provider_types": ["DIGITALOCEAN", "HETZNER"],
"tf_use_workspace": False,
"tf_terraform_semantic_version": "1.4.2",
"do_as_backend": True,
"do_bucket": "your-bucket",
}
build = DevopsTerraformBuild(project, config)
build.initialize_build_dir()
@task
def plan(project):
build = get_devops_build(project)
build.plan()
@task
def apply(project):
build = get_devops_build(project)
build.apply(True)
@task
def destroy(project):
build = get_devops_build(project)
build.destroy(True)
```
## Release
```
adjust version no in build.py to release version no.
git commit -am "release"
git tag -am "release" [release version no]
git push --follow-tags
increase version no in build.py
git commit -am "version bump"
git push
pip3 install --upgrade --user ddadevops
```
