# TODO
# TODO: `terraform-provider-melange`
### Installing
```
terraform {
required_providers {
melange = { source = "imjasonh/melange" }
}
}
```
Then `terraform init -upgrade`.
(This is not yet published; it will be published under `chainguard-dev` when it's ready)
### Build a single package
```
provider "melange" {
@ -7,6 +23,23 @@ provider "melange" {
extra_keyring = ["https://packages.wolfi.dev/os/wolfi-signing.rsa.pub"]
}
data "melange_config" "config" {
config_contents = file("package.yaml")
}
resource "melange_build" "package" {
config = data.melange_config.config.config
config_contents = data.melange_config.config.config_contents
}
```
After applying this config, `packages/$ARCH/package-0.0.1-rX.apk` will be built, and `packages/$ARCH/APKINDEX.tar.gz` will be updated.
(This passes locally but currently fails in CI...)
### Build a graph of inter-dependent Melange configs
```
data "melange_graph" "graph" {
files = fileset(path.module, "*.yaml")
}
@ -15,6 +48,41 @@ resource "melange_build" "foo" {
for_each = data.melange_graph.graph.configs
depends_on = data.melange_graph.graph.deps[each.key]
config = each.key
config = each.key
config_contents = data.melange_graph.graph[each.key].config_contents
}
```
This will crawl a collection of Melange config files, construct a graph of the order they should be built to ensure dependencies are met, and build them in that order with Terraform's configured concurrency.
(This is not yet implemented)
### Build a package locally, then build it into an image using `apko_build`
```
data "melange_config" "config" {
config_contents = file("package.yaml")
}
resource "melange_build" "package" {
config = data.melange_config.config.config
config_contents = data.melange_config.config.config_contents
}
provider "apko" {
archs = ["x86_64", "aarch64"]
extra_repositories = ["https://packages.wolfi.dev/os", "./packages"]
extra_keyring = ["https://packages.wolfi.dev/os/wolfi-signing.rsa.pub", "./local-signing.rsa.pub"]
}
data "apko_config" "config" {
config_contents = file("image.yaml")
extra_packages = [data.melange_config.config.config.package.name]
}
resource "apko_build" "image" {
config = data.apko_config.config.config
}
```
(This is not yet tested)
