OpenTUNA will be sunsetted from 20th Dec 2023. This repository will then be archived and no longer maintained.
If you are interested in future maintenance work, feel free to reach us at https://github.com/tuna/issues/issue.
This is the infrastructure project of Open TUNA on AWS, orchestrated by AWS CDK.
See below for the overall architecture,
It consists of the following independent stacks,
- Network stack(optional)
- Create a dedicated VPC with public and private subnets across three AZs with NAT gateways
- Create S3 Endpoint
- Storage stack(optional)
- EFS file system
- Common stack
- SNS notification topic
- Slack webhook subscription(optional)
- Open TUNA stack
- S3 asset bucket
- application load balancer
- CloudFront distribution
- log analysis for CloudFront distribution
- ECS cluster for content server and web portal
- issue SSL certificate from ACM(only for using Route53 as DNS resolver)
- create DNS record in R53 for ALB and CloudFront(only for using Route53 as DNS resolver)
- invalidate CloudFront cache when content updates
- S3 buckets for S3-backed repos e.g. rubygems
- Tunasync Manager stack
- auto scaling group for tunasync manager
- intranet application load balancer for manager's API
- elasticache redis cluster for database storage
- Tunasync Worker stack
- auto scaling group for tunasync worker
- install necessary third party tools for mirroring tasks
- use systemctl as daemon to start tunasync worker
- send custom CloudWatch metrics of tunasync process info
- publish large configuration files to s3 asset bucket
- Content Server stack
- build custom nginx container
- use Fargate service to serve mirror contents
- internet facing application load balancer
- collect network metrics by CloudWatch agent
- setup auto scaling rules based on metrics
- Web Portal stack
- use tuna/mirror-web
- route tunasync.json to tunasync manager
- create and run lambda function periodically to generate iso download links
- Monitor stack
- create several CodeBuild projects to verify integrity of index files
- run projects periodically and report upon failure
- trigger re-sync when failure is detected
- Certificate stack
- create CodeBuild project to manual renew Let's Encrypt certificate
- Pipeline stack
- VPC with both public and private subnets crossing two AZs at least and NAT gateway. You can deploy the network stack if you don't have a VPC which satisfies the requirements.
- EFS file system associated with above VPC. You can deploy stack with provisioning a EFS file system without specifying the existing filesystem id of EFS.
- An AWS account
- Configure credential of aws cli
- Install node.js LTS version, such as 12.x
- Install npm 7.x
- Install Docker Engine

npx cdk deploy OpenTunaStorageStack -c vpcId=<existing vpc Id>
# deploy storage and common stack as well
npx cdk deploy OpenTunaStack -c vpcId=<existing vpc Id>
# subscribe SNS topic alaram to slack channel
# Go to https://slack.com/apps/A0F7XDUAZ-incoming-webhooks to apply for webhook
npx cdk deploy OpenTunaStack -c vpcId=<existing vpc Id> -c slackHookUrl=<webhook url>
# or deploy with existing EFS filesystem
npx cdk deploy OpenTunaStack -c vpcId=<existing vpc Id> -c fileSystemId=<existing filesystem id> -c fileSystemSGId=<existing sg id of the given file system>
# deploy with domain name and use Route53 as DNS resolver
npx cdk deploy OpenTunaStack -c vpcId=<existing vpc Id> -c domainName=<domain name of site> -c domainZone=<public hosted zone of your domain in Route53>
# deploy with SSL cert of CloudFront for China regions
# upload SSL cert to IAM, for China region only
aws iam upload-server-certificate --server-certificate-name my-domain --certificate-body file://cert.pem --private-key file://privkey.pem --certificate-chain file://chain.pem --path '/cloudfront/'
# get cert id from above output
npx cdk deploy OpenTunaStack -c vpcId=<existing vpc Id> -c domainName=<domain name of site> -c domainZone=<public hosted zone of your domain in Route53> -c iamCertId=<cert id>
The CertificateStack
will be created when using IAM cert for the CloudFront SSL. The stack will create a CodeBuild project to issue new SSL certificates from Let's encrypt. And the build event can be pushed to the pipeline account when deploying the stack via the below context option,
-c certTopicArn=<arn of sns topic created by pipeline stack>
Docker image for content server is automatically built and published. You can build and publish to ecr manually:
$ sudo docker build -t content-server:1.18-alpine .
$ sudo docker tag content-server:1.18-alpine ${uid}.dkr.ecr.${region}.amazonaws.com/content-server:1.18-alpine
$ sudo docker push ${uid}.dkr.ecr.${region}.amazonaws.com/content-server:1.18-alpine
npm run test
- Add email addresses or other subscribers to the notification topic created in the common stack. The alarm notifications related to Open TUNA will be sent to those subscribers.
