DIY Container PaaS
A DIY container PaaS for self-serviced container deployments.
Status: NOT FOR PRODUCTION USE
Use at your own risk!
Motivation
Budget container PaaS solution that offers portable, self-serviced container deployments, and don't want to worry too much about:
- backups
- node failures
- scaling
- PaaS vendor lock-ins
Features
Basic
- Terraform to automate provisioning of docker swarm clusters on Vultr
- ability to add more nodes as you need them
- Docker Swarm for container orchestration
- Traefik for reverse proxy service (aka ingress) with automated SSL cert creation
- GlusterFS clustered file system for:
- container portability across the cluster
- replicated storage
Extended
- Better documentation
- Load balanced ingress with health-checks
- Multi-master management nodes
- Support for DigitalOcean
Advanced
- Replace failed nodes
- Dedicated roles, e.g. databases, message queues, etc
- Centralized logging
Quick Start
Configure your terraform configuration main.tf
module "mini-pass-example" {
source = "/tf_modules/mini-paas/vultr"
cluster_name = "example-cluster"
cluster_worker_count = 1
//cluster_instance_price_per_month = "10.00"
//cluster_ram_mb = "2048"
//cluster_region = "Singapore"
dns_domain = "example.com"
dns_acme_email = "email@example.com"
ssh_key_source = "/deployment/resources/example_rsa"
ssh_key_name = "example"
}Run the terraform container
# Mount your terraform configuration folder to the "/deployment" folder
docker run --rm -it -v $(pwd)/example:/deployment/ -e VULTR_API_KEY=<your-vultr-api-key> ronalddddd/mini-paas
# You are now inside the docker container's terraform environment
/deployment # terraform init
/deployment # terraform plan
/deployment # terraform applyStart using your cluster
# Shell into your swarm manager
ssh -i /path/to/your/sshkey root@example.com
# Check the cluster
docker node ls
# Check what's running
docker node ps
An example service is deployed as well. You should now be able to browse to http://whoami.example.com and get redirected to a https version.
See tf_modules/mini-paas/resources/debugging/docker-compose.yml for an example on deploying a web service with automatic domain and SSL setup.
