quickstart-mongodb-atlas

MongoDB Atlas in the AWS Cloud

This Quick Start provisions complete MongoDB Atlas deployments through CloudFormation using official MongoDB Atlas AWS CloudFormation Resource Types.

Quick Start architecture for MongoDB Atlas on AWS

Includes support for:

  • MongoDB Atlas Projects
  • MongoDB Atlas Clusters
  • MongoDB Atlas Database Users via AWS IAM Integration
  • VPC Peering

For architectural details, best practices, step-by-step instructions, and customization options, see the deployment guide.

To post feedback, submit feature ideas, or report bugs, use the Issues section of this GitHub repo. If you'd like to submit code for this Quick Start, please review the AWS Quick Start Contributor's Kit.

Getting Started

Setup AWS & API Keys

If needed, install the awscli and mongocli.

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "/tmp/awscliv2.zip"
unzip /tmp/awscliv2.zip
sudo /tmp/aws/install
MONGOCLI_VERSION="1.7.0"
curl -L "https://github.com/mongodb/mongocli/releases/download/${MONGOCLI_VERSION}/mongocli_${MONGOCLI_VERSION}_linux_x86_64.tar.gz" -o "/tmp/mongocli_${MONGOCLI_VERSION}_linux_x86_64.tar.gz"
tar xzvf "/tmp/mongocli_${MONGOCLI_VERSION}_linux_x86_64.tar.gz" --directory /tmp
cp "/tmp/mongocli_${MONGOCLI_VERSION}_linux_x86_64/mongocli" "~/.local/bin"
~/.local/bin/mongocli --version

Make sure to configure each tool properly.

aws configure
mongocli config
  • Run this helper to setup environment variables for your MongoDB Atlas API keys (read from mongocli config)
source <(./scripts/export-mongocli-config.py)

Deploy the MongoDB Atlas Resource Types into your AWS region.

This quickstart is powered by a set of official MongoDB AWS CloudFormation Resource Types which connect your AWS CloudFormation control plane directly into the MongoDB Cloud. Right now, these resources need to be registered in each AWS region prior to use.

Run this command to install the MongoDB Atlas Resource Types into the AWS_REGION of your choice before running the quickstart.

cd mongodbatlas-cloudformation-resources\cfn-resources
./cfn-submit-helper.sh project cluster database-user project-ip-access-list network-peering

Launch the quickstart stack

The quickstart-mongodb-atlas.template.yaml template will provision a complete you MongoDB Atlas Deployment for you.

This includes the follow resources:

repo_root=$(git rev-parse --show-toplevel)
source <(${repo_root}/quickstart-mongodb-atlas/scripts/export-mongocli-config.py)
${repo_root}/quickstart-mongodb-atlas/scripts/launch-x-quickstart.sh ${repo_root}/quickstart-mongodb-atlas/templates/quickstart-mongodb-atlas.template.yaml MongoDB-Atlas-Quickstart ParameterKey=OrgId,ParameterValue=${ATLAS_ORG_ID} 

The stack will take ~7-10 minutes to provision. When complete you can find the mongodb+srv connection information in the stack outputs.

aws cloudformation describe-stacks --stack-name ${STACK_NAME} | jq -r '.Stacks[0]|.Outputs'

When complete, you can connect using the mongo shell.

Connect to your database

After the cluster provisions, you can connect with the mongo shell or MongoDB Compass.

Fetch the new cluster mongodb+srv:// host info:

STACK_NAME="mongodb-atlas-quickstart"
MDB=$(aws cloudformation list-exports |\
 jq -r --arg stackname "${STACK_NAME}" \
 '.Exports[] | select(.Name==$stackname+"-standardSrv") | .Value')
echo "New ${STACK_NAME} database url: ${MDB}"

Use this url along with your aws cli credentials to seamlessly and securly connect to your new MongoDB Atlas database:

STACK_ROLE=$(aws cloudformation describe-stack-resources --stack-name "${STACK_NAME}" --logical-resource-id AtlasIAMRole)
ROLE=$(aws iam get-role --role-name $( echo "${STACK_ROLE}" | jq -r '.StackResources[] | .PhysicalResourceId'))
ROLE_ARN=$(echo "${ROLE}" | jq -r '.Role.Arn')
ROLE_CREDS=$(aws sts assume-role --role-session-name test --role-arn ${ROLE_ARN})
mongo "${MDB}/${STACK_NAME}?authSource=%24external&authMechanism=MONGODB-AWS" \
    --username $(echo "${ROLE_CREDS}" | jq -r '.Credentials.AccessKeyId') \
    --password $(echo "${ROLE_CREDS}" | jq -r '.Credentials.SecretAccessKey') \
    --awsIamSessionToken $(echo "${ROLE_CREDS}" | jq -r '.Credentials.SessionToken')

see scripts/aws-iam-mongo-shell.sh.

Launch the quickstart stack with Peering

The quickstart-mongodb-atlas-peering.template.yaml stack will provision a complete you MongoDB Atlas Deployment with VPC Peering for a given AWS VPC enabled.

This includes the follow resources:

repo_root=$(git rev-parse --show-toplevel)
source <(${repo_root}/quickstart-mongodb-atlas/scripts/export-mongocli-config.py)
${repo_root}/quickstart-mongodb-atlas/scripts/launch-x-quickstart.sh ${repo_root}/quickstart-mongodb-atlas/templates/quickstart-mongodb-atlas-peering.template.yaml MongoDB-Atlas-Quickstart ParameterKey=OrgId,ParameterValue=${ATLAS_ORG_ID}  ParameterKey=RouteTableCIDRBlock,ParameterValue=192.168.0.0/24 ParameterKey=VPC,ParameterValue=<YOUR_VPC_ID> 

The stack will take ~7-10 minutes to provision. When complete you can find the mongodb+srv connection information in the stack outputs.

aws cloudformation describe-stacks --stack-name ${STACK_NAME} | jq -r '.Stacks[0]|.Outputs'

TODO add steps for connect with vpc, add a test lambda function in vpc?
