(Deis + Kubernetes + AWS) for the win
I like to use deis because I can deploy my projects just like heroku while I can play with kubernetes. So I setup deis on aws. I wanted to use http2 and I can't use http2 ports on heroku.
- deploy kubernetes with tack
- install deis with helmc
- setup DNS and Letsencrypt certs
I used https://github.com/kz8s/tack for setting up kubernetes on AWS.
- change name of region in
- if kubectl is not working, check the path of
io.tfyou can change kubernetes version. visit "quay.io/coreos/hyperkube" and check the latest tag.
~/.kube/config, there would be settings for previous builds.
~/.helmcand delete cache and workspace folders. (in case you changed the path of
we are gong to use Helm to manage packages for kubernetes.
curl -sSL http://deis.io/deis-cli/install-v2.sh | bash mv deis /usr/local/bin curl -sSL https://get.helm.sh | bash mv $PWD/helmc /usr/local/bin/helmc helmc target # Ensure the kubectl client is installed and # can connect to your Kubernetes cluster.
CAUTION. UPDATE ROLES TO worker and master role. then visit https://console.aws.amazon.com/iam/home?region=ap-southeast-1#roles. Add ec2, rds, s3, ecs roles to worker .
if you want to change config for workflow, check deis-s3-db-registry folder
helmc fetch deis/workflow-v2.7.0 # fetches the chart into a # local workspace
At this point, You may want to configure s3 and postgres for deis.
On aws, after creating the postgres db, add a inboud rule to the security group like this so that local machine or deis can connect to it.
Security Group Rules - Edit inbound rules TCP 5432 Anywhere 0.0.0.0/0
For s3, Ater creating 3 bukcets, you need to add more permission to the IAM role. visit https://console.aws.amazon.com/iam/home?region=ap-southeast-1#roles and add s3 related permissions to worker-k8s-rpc, master-k8s-rpc
currently, I am not using ecr for registry. For custom domains, you may want to add route53 related permissions to those roles too.
If you want to use ecr then visit https://ap-southeast-1.console.aws.amazon.com/ecs/home?region=ap-southeast-1#/firstRun and setup cluster then change the
change s3 or rds related config before you run
helmc generate -x manifests workflow-v2.7.0 # generates various secrets helmc install workflow-v2.7.0 # injects resources into # your cluster kubectl --namespace=deis get pods #-> should return more than 10 pods
Configure your AWS Load Balancer for
git push. Set the timeout to 3600.
configuring a load balancer¶
kubectl --namespace=deis annotate deployment/deis-router router.deis.io/nginx.useProxyProtocol=true kubectl --namespace=deis annotate service/deis-router service.beta.kubernetes.io/aws-load-balancer-proxy-protocol='*'
and then register to your server
deis register http://deis.example.com admin / ******
deis keys:add. For setting up DNS records, check the following section.
Naked domain for a deis project
I have several domains for projects. let’s say 2 for deis hub and 1 for my project. Assume that example.com is our project and root.io and root.co are my hub domains. I am using AWS and Cloudflare to achieve naked domain.
add domains to the repo
deis domains:add example.com deis domains:add www.example.com deis domains:add unbent-backbone.root.io
add a url forwarding page rule: match "www.example.com/*" with "https://example.com/$1"
# DNS Setup for example.com on cloudflare CNAME www unbent-backbone.root.io (orange) CNAME @ unbent-backbone.root.io (orange) # DNS Setup for root.io on cloudflare CNAME @ hub.root.co (!! NO ORANGE) CNAME deis hub.root.co (orange) CNAME deis-builder hub.root.co (!! NO ORANGE) CNAME unbent-backbone hub.root.co (orange)
setup the alias for elb
# DNS Setup for root.co on AWS Route53 A hub.root.co Alias Target dualstack.xxx.ap-southeast-1.elb.amazonaws.com
1) do nothing for aws elb
2) use cloudflare for https assets
kube-cert-manager.based on https://github.com/PalmStoneGames/kube-cert-manager, it works. I just had to change
psg to my domain in the project files. and build
kube-cert-managerexecutable file. And then I build the docker image and published it.
Uninstall / Reinstall
if you are going to reinstall, do not delete elb.
cd .helmc helmc uninstall workflow-v2.7.0 -n deis cd tack make clean
check vpc, elb, s3 buckets
change the name of instance in tack's Makefile
before install, check to regions in ~/.aws/ and ~/.deis and tack's Make file
or any ENV vars. ~/.zsh_aliase has ENV var to access AWS!
