DataHub Watchtower

This application is part of the DataHub Project.

DataHub is a Cloud Development Ecosystem aiming to bring the power of Dart into the Cloud.

DataHub is still under development and is not to be considered production ready. Comprehensive documentation is yet to
be released.

Configuration #
This service requires at least one configuration file.
Provide the configuration file as command line argument.
You can split configuration files (f.e. config / secrets) into multiple files
and provide every separate file as an argument.
You can find the debug configuration file here:
resources/debug.yaml
Run Service in Dart VM #
Dart code can be executed without compiling.
Requirements

Dart ≥ 2.17 (Setup)

Get Dependencies
$ dart pub get

Run Code Generator
$ dart run build_runner build
copied to clipboard
Run
$ dart run bin/datahub_watchtower.dart resources/debug.yaml
copied to clipboard
Compile and Run #
Compiled code runs faster, so this is the preferred method for deployment.
The resulting executable will be named bin/datahub_watchtower.exe.
The file extension is exe on linux or mac too, don't worry about it.

Build Debug Docker Image #
Requirements

Docker ≥ 1.8 (Setup)

This image will run the service in the vm. Code generation must be done on the host machine
first. The image will build very fast (no compile time) but the service itself will run a little slower.
This is only recommended for development / testing purposes.
The resulting docker image will use the debug configuration: resources/debug.yaml.
Get Dependencies
$ dart pub get

Build using DataHub CLI #
DataHub CLI will run the code generator, build the debug docker image and automatically tag
it as datahub_watchtower:debug.
Build
$ datahub build -d
copied to clipboard
Build using Docker CLI #
When building debug images manually, make sure to run code generation first:
Run Code Generator
$ dart run build_runner build
copied to clipboard
Build
$ docker build -t datahub_watchtower:debug -f Dockerfile.debug .
copied to clipboard
Build Release Docker Container #
Requirements

Docker ≥ 1.8 (Setup)

The resulting docker image will expect a config file at /app/config.yaml.
Best practice is to provide this config file via bind mount (Docker)
or ConfigMap / Secrets (Kubernetes).
Build using DataHub CLI #
DataHub CLI will build the release docker image and automatically and tag
it as datahub_watchtower:latest and datahub_watchtower:{version}.
Build
$ datahub build

Build using Docker CLI #
Build and Tag
$ docker tag datahub_watchtower:latest datahub_watchtower:{version}
$ docker build -t datahub_watchtower:latest .
