Backstage repo-components template (Version 0.0.1)

To install these components into your repo simply run following command:

Wget:

wget https://github.com/bitswar/backstage-components-template/releases/download/0.0.1/install.sh && chmod +x install.sh && ./install.sh

Curl:

curl -L https://github.com/bitswar/backstage-components-template/releases/download/0.0.1/install.sh -o install.sh && chmod +x install.sh && ./install.sh

This command will create cataog folder in the place where you are locating. To add your components into Backstage simply specify link to your main.yaml file in the dialog.

API

Remove providing:

If you don't need to provide API documentation follow this steps:

1. Remove api folder in catalog/api
2. Remove catalog/apis.yaml
3. Delete line with apis.yaml in main.yaml:

apiVersion: backstage.io/v1aplha1
kind: Location
metadata:
  name:  ${MAIN_NAME}
  description: ${MAIN_DESCRIPTION}
spec:
  targets:
    - ./apis.yaml # Delete this line

After these steps you won't provide APIs documentation into Backstage

---

API configuration steps:

If you need to provide some APIs the best way is to have separated files for Backstage components and files with schemas. In the example there are 2 files: example.yaml with Backstage component and example.oas.yaml with schema where oas means Open API Scheme.

If you need to add new scheme follow these steps:

1. Add file with description of new scheme for example new-scheme.yaml

   apiVersion: backstage.io/v1alpha1
   kind: API
   metadata:
       name: Example API
       description: Example API of scaffolded project
   spec:
       type: openapi
       lifecycle: production
       owner: guest
       system: examples
       definition:
           $text: new-schmeme.oas.yaml

2. Add scheme with OpenAPI in `new-scheme.oas.yaml
3. Add new-scheme.yaml to array in catalog/apis.yaml

apiVersion: backstage.io/v1alpha1
kind: Location
metadata:
  name: ${API_LOCATION_MAME}
  description: ${API_LOCATION_DESCRIPTION}
spec:
  targets:
    - ./api/example.yaml
    - ./api/new-scheme.yaml

3. Reload components in Backstage

If you need another scheme check Backstage documentation and choose apropriate type for the scheme

Documentation

Disabling PlantUML

If you're not using PlantUML for diagrams you can remove in from this structure:

1. Go to catalog/mkdocs.yaml
2. Remove plantuml-colocator from array of plugins
3. Remove line 14 and 16 from makefile. By removing them you will disable preprocessing PlantUML files for generation documantation for publishing

   ...
   .PHONY: generate
   generate:
   ifneq ($(origin DEFAULT_SRC_DIR), undefined)
   ifneq ($(origin DEFAULT_OUT_DIR), undefined)
       @echo "DEFAULT"
       @make -- --preprocess # Remove this line
       @npx @techdocs/cli generate --source-dir $(DEFAULT_SRC_DIR) --output-dir $(DEFAULT_OUT_DIR) --no-docker
       @make -- --restore # Remove this line
   else
   ...

Publishing documentation to S3 buckets

You should specify .env file in derictory from where you call Make functions.Is should be located in catalog/.env:

# S3 settings
S3_ENDPOINT=https://storage.company.com
S3_BUCKET=public
S3_REGION=us-east-1
S3_ACCESS_KEY_ID=your-access-key-id
S3_SECRET_ACCESS_KEY=your-access-key-secret
S3_TYPE=awsS3

# PlantUML generation
DEFAULT_SRC_DIR=.
DEFAULT_OUT_DIR=./site

# Backstage entity description
BACKSTAGE_ENTITY=default/Component/Documentation

PlantUML generation

If you're using PlantUML add variables for generation settings:

# PlantUML generation
PUML_INCLUDE_DIR=docs/utils/
PUML_ROOT_DIR=docs/

• PUML_INCLUDE_DIR and/or PUML_INCLUDE_DIR_* for adding directories with files that should be included to another .puml fiels (like stylings or predefined functions)
• PUML_ROOT_DIR is root dir where all .puml files are located

Commands

Generation documentation

To generate documentation run the command:

make generate

By default it gets documentation from the root folder where you located $(pwd) and stores generated documentation to ./site folder

Be sure that in you root folder file mkdocs.yaml exists

If you wanna customize directories you can add parameters to command:

make generate src=. out=./site

Where src is directory from where script will take .md files and out where documentation will be saved

Publishing documentation

To publish doumentation run the command:

make publish

It will get all environment from .env file and try to publish documentation to bucket that you specified

Publish with Docker image

To publish documentation without installing dependencies can be used simple docker image that already has all of them. Only docker daemon is required.

To generate & publish documentation should be called following command:

$ docker run --env-file [path-to-env-file] -v [path-to-folder-with-docs]:/docs danysmall/mkdocs-scaffold:latest

As an example if we're running this command from catalog page where our documentation is locaded (*.yaml files, mkdocs.yaml and others) we can use it like:

$ docker run --env-file .env -v .:/docs danysmall/mkdocs-scaffold:latest

and it's gonna build and push all documentation without touching original one
