# Carvel ytt rules for Bazel
## Setup
Add to `WORKSPACE` file.
```starlark
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
name = "com_github_ebay_rules_ytt",
sha256 = "0232522fd7a07d2eb0a47fe4ec3a6dc8bc8e0bcbaa8abd658c6be53a34f5bd76",
strip_prefix = "rules_ytt-0.1.0",
urls = [
"https://github.com/eBay/rules_ytt/releases/download/v0.1.0/rules_ytt-0.1.0.zip",
],
)
load("@com_github_ebay_rules_ytt//:deps.bzl", "ytt_rules_dependencies")
ytt_rules_dependencies()
```
## Usage
Add to `BUILD` file:
```starlark
load("@com_github_ebay_rules_ytt//:def.bzl", "ytt")
load("@io_bazel_rules_docker//go:image.bzl", "go_image")
go_image(
name = "image",
srcs = ["main.go"],
importpath = "...",
)
ytt(
name = "manifests",
srcs = [
":base.yaml",
":defaults.yaml",
":values.yaml",
],
image = ":image.digest",
)
```
Which is equivalent to
```shell
ytt -f base.yaml -f defaults.yaml -f values.yaml --dangerous-allow-all-symlink-destinations
```
* `bazel build //:manifests` - generates yaml files and store it in cache.
* `bazel run //:manifests` - prints generated yaml files to stdout.
* `bazel run //:manifests | kubectl -n -f -` - applies generated manifests to k8s cluster.
Image digest is available inside yaml templates as `data.values.image_digest`.
