Supergiant: Easy container orchestration using Kubernetes

Supergiant is an open-source container orchestration system that lets developers easily deploy and manage apps as Docker containers using Kubernetes.

Supergiant aims to automate installation and simplify management of Kubernetes across different cloud accounts by providing an easy-to-use UI that exposes Kubernetes API. The system implements simple concepts that abstract Kubernetes API for pod and services deployment, storage, load-balancing, hardware auto-scaling, and more. Supergiant uses an efficient packing algorithm to enable seamless auto-scaling of Kubernetes clusters to minimize costs and improve resilience of applications. For a more detailed overview of Supergiant top-level concepts, see the docs folder.

Features

Fully compatible with native Kubernetes (works with existing setups)
UI and CLI, both built on top of an API (with importable Go client lib)
Launch and manage multiple Kubes across multiple cloud providers from the UI
Works with multiple cloud providers (AWS, DigitalOcean, OpenStack, Packet.net, and actively adding more, in addition to on-premise hardware support)
Deploy / Update / Restart containers with a few clicks
Get instant access to apps from Helm Repositories
Filterable container metrics views (RAM / CPU timeseries graphs)
Get a comprehensive view of cluster resources with built-in monitoring and logging
Automatic server management (manual addition of new nodes, background server autoscaling, up/down depending on container resource needs)
Role-based Users, Session-based login, self-signed SSL, and API tokens for security (OAuth and LDAP support soon coming)

Installation

Download the Supergiant server for your system (Windows, Mac, and Linux) and processor architecture from our releases page. For example, for Linux:

curl https://github.com/supergiant/supergiant/releases/download/v0.15.6/supergiant-server-linux-amd64 -L -o /usr/bin/supergiant

Make sure to make the downloaded binary executable:

sudo chmod +x /usr/bin/supergiant

Download the example config file and customize it:

curl https://raw.githubusercontent.com/supergiant/supergiant/master/config/config.json.example --create-dirs -o /etc/supergiant/config.json

In the configuration file, specify your paths to log and database locations and create corresponding directories for them.

{
 ...
 "sqlite_file": "/var/lib/supergiant/development.db",
 ...
 "log_file": "/var/log/supergiant/development.log",
 ...
}

Run the binary with a config file and save the user/password for the admin user generated the first time Supergiant runs.

<supergiant-server-binary> --config-file /etc/supergiant/config.json

Access Supergiant on default 8080 port on localhost.

Installing on AWS

If you want to easily install Supergiant on Amazon Web Services EC2 with Supergiant Amazon Machine Image (AMI), follow the Supergiant AWS Install Tutorial.

Usage

Deploying Kubernetes Cluster

Supergiant allows deploying Kubernetes clusters (Kubes) via the easy-to-use interface with the minimal configuration required. The system manages Kubernetes installation and configuration under the hood enabling various master and nodes services and tools.

Deploying Apps from Helm Repositories

Supergiant provides access to Kubernetes curated helm charts with a broad choice of configured containers installable in one click.

Tracking Cluster Resources

Supergiant UI gives a comprehensive view of computer resources used by the cluster, running applications, services, and attached storages to get insights and simplify cluster administration.

Micro-Roadmap

Currently, the core team is working on the following:

Add LDAP and OAuth user authentication
Add support for new cloud providers
Add support for local installations

Resources

Community and Contributing

We are grateful for any contribution to the Supergiant project be it in a form of a new GitHub issue, a GitHub feature Pull Request, social media engagement etc. Contributing to Supergiant projects requires familiarization with Community and our Contribution Guidelines. Please see these links to get started.

Development

Use Docker in development

docker-compose build server
docker-compose run --rm --service-ports server

Native go on your host

If you would like to contribute changes to Supergiant, first see the pages in the section above, Community and Contributing.

Note: Supergiant cloud installers have dependencies pre-installed and configured and will generate a self-signed cert based on the server hostname. These instructions are for setting up a local or custom environment.

Supergiant dependencies:

Git
Go version 1.7+
Govendor for vendoring Go dependencies

Checkout the repo

go get github.com/supergiant/supergiant

Create a Config file

You can copy the example configuration:

cp config/config.json.example config/config.json

Run Supergiant

go run cmd/server/server.go --config-file config/config.json
open localhost:8080

Build the CLI

This will allow for calling the CLI with the supergiant command:

go build -o $GOPATH/bin/supergiant cmd/cli/cli.go

Run Tests

govendor test +local

Saving dependencies

If you make a change and import a new package, run this to vendor the imports.

govendor add +external

Compiling Provider files, UI templates, and static assets

Supergiant uses go-bindata to compile assets directly into the code. You will need to run this command if you're making changes to the UI or if you're working with Provider code:

go-bindata -pkg bindata -o bindata/bindata.go config/providers/... ui/assets/... ui/views/...

Enabling SSL

Our AMI distribution automatically sets up self-signed SSL for Supergiant, but the default config/config.json.example does not enable SSL.

You can see our AMI boot file for an example of how that is done if you would like to use SSL locally or on your own production setup.
