Deploy Magda to AWS

1> Create EKS cluster on AWS using eksctl

Amazon Elastic Kubernetes Service (Amazon EKS) is a managed service that you can use to run Kubernetes on AWS without needing to install, operate, and maintain your own Kubernetes control plane or nodes.

eksctl is a simple CLI tool for creating clusters on EKS - Amazon’s new managed Kubernetes service for EC2. It is written in Go, and uses CloudFormation.

You can follow the AWS tutorial document below to create an EKS cluster using eksctl:

https://docs.aws.amazon.com/eks/latest/userguide/getting-started-eksctl.html

More usage info of eksctk can be found from: https://eksctl.io/

2> Create a kubeconfig for Amazon EKS

You need to setup kubeconfig so you can use kubectl connect to / manage your cluster or use helm to install Magda

aws eks --region <region-code> update-kubeconfig --name <cluster_name>

More details can be found from: https://docs.aws.amazon.com/eks/latest/userguide/create-kubeconfig.html

3> Create AWS PostgreSQL Database (Optional)

You can also choose to use the in-pod PostgreSQL database that comes with Magda helm charts. But for production deployment, it’s recommanded to use cloud provider hosted database i.e. Create AWS PostgreSQL Database

Please note: you need to create master db user in name “postgres” due to this issue.

To make EKS cluster be able to connect to the RDS database created, you need to make sure the followings are in place:

You can use RDS Endpoint domain e.g. xxxx.xxx.[region name].rds.amazonaws.com to connect to the RDS from your EKS cluster.

4> Install kubernetes-replicator

It’s only required by the OpenFaas part of Magda which can be turned off via global.openfaas.enabled.

# add helm chart repo
helm repo add mittwald https://helm.mittwald.de

# update helm chart repo
helm repo update

# create namespace `kubernetes-replicator`
kubectl create namespace kubernetes-replicator

# Install kubernetes-replicator via helm
helm upgrade --namespace kubernetes-replicator --install kubernetes-replicator mittwald/kubernetes-replicator

5> Create a namespace “magda” for your Magda installation

kubectl create namespace magda

6> Create required secrets in Magda deployment namespace magda

You need pwgen command line tool to follow the instruction below. If it’s not availble on nyour system, you need to install one.

export JWT_SECRET="$(pwgen 32 1)"
export SESSION_SECRET="$(pwgen 32 1)"
# this is the password for a DB account auto created by Magda using master DB account
export DB_PASSWORD="$(pwgen 32 1)"
export MINIO_ACCESS_KEY="$(pwgen 32 1)"
export MINIO_SECRET_KEY="$(pwgen 32 1)"

# This is your DB master user account password
export DB_MASTER_PASSWORD="Your Master DB PASSWORD"
# for sending inquiry emails
export SMTP_USERNAME="Your SMTP USERNAME"
export SMTP_PASSWORD="Your SMTP PASSWORD"


kubectl create secret generic cloudsql-db-credentials --namespace magda --from-literal=password=$DB_MASTER_PASSWORD

kubectl create secret generic auth-secrets --namespace magda --from-literal=jwt-secret=$JWT_SECRET --from-literal=session-secret=$SESSION_SECRET

kubectl --namespace magda annotate --overwrite secret auth-secrets replicator.v1.mittwald.de/replication-allowed=true replicator.v1.mittwald.de/replication-allowed-namespaces=magda-openfaas-fn

kubectl create secret generic db-passwords --namespace magda \
--from-literal=combined-db=$DB_PASSWORD \
--from-literal=authorization-db=$DB_PASSWORD \
--from-literal=content-db=$DB_PASSWORD \
--from-literal=session-db=$DB_PASSWORD  \
--from-literal=registry-db=$DB_PASSWORD \
--from-literal=combined-db-client=$DB_PASSWORD \
--from-literal=authorization-db-client=$DB_PASSWORD \
--from-literal=content-db-client=$DB_PASSWORD \
--from-literal=session-db-client=$DB_PASSWORD \
--from-literal=registry-db-client=$DB_PASSWORD \
--from-literal=tenant-db=$DB_PASSWORD \
--from-literal=tenant-db-client=$DB_PASSWORD

kubectl create secret generic storage-secrets --namespace magda --from-literal=accesskey=$MINIO_ACCESS_KEY --from-literal=secretkey=$MINIO_SECRET_KEY

kubectl create secret generic smtp-secret --namespace magda --from-literal=username=$SMTP_USERNAME --from-literal=password=$SMTP_PASSWORD

If you use authentication plugins, you might need to create extra secrets as required.

7> Add Magda Helm Repo

helm repo add magda-io https://charts.magda.io
helm repo update

8> Install Magda via Helm

helm upgrade --namespace magda --install --timeout 9999s --set magda-core.gateway.service.type=LoadBalancer magda magda-io/magda

By default, it will use in pod postgresSQL database. To use RDS, you need to set extra values as blow:

# Set RDS endpoint domain
export RDS_ENDPOINT=xxxx.xxx.[region name].rds.amazonaws.com

helm upgrade --namespace magda --install --timeout 9999s --set magda-core.gateway.service.type=LoadBalancer,global.useCombinedDb=false,global.useCloudSql=false,global.useAwsRdsDb=true,global.awsRdsEndpoint=$RDS_ENDPOINT magda magda-io/magda

By default, Helm will install the latest production version of Magda. You can use --version to specify the exact chart version to use. e.g.:

helm upgrade --namespace magda --install --version 0.0.60-rc.1 --timeout 9999s --set magda-core.gateway.service.type=LoadBalancer magda magda-io/magda

The value --set magda-core.gateway.service.type=LoadBalancer will expose Magda via load balancer (AWS ELB).

You can run:

echo $(kubectl get svc --namespace magda gateway --template "")

to find out the load balancer external IP. And access Magda via http://[External IP].

To expose Magda via Ingress and Setup TLS / SSL, you can follow this docs
