DEVNET-1144 Deploying hybrid cloud applications with HashiCorp Atlas
3 likes1,010 views
The document discusses HashiCorp's tools such as Vagrant, Packer, Consul, Terraform, and Vault, outlining their functionalities in creating, managing, and deploying applications in hybrid cloud environments. It introduces Atlas as a unified platform that integrates these tools to provide a streamlined application delivery process and governance. Additionally, it includes a demonstration of building and deploying an AWS artifact using Packer and Terraform, showcasing automation and multi-cloud capabilities.

- 6. VAGRANT • One command development environments • Virtual machines or containers • Any environment: PHP, Ruby, Python, Java, etc. • Millions of downloads per month
- 7. PACKER • One command to build deployable ar+facts • Amazon, OpenStack, Docker, VMware, KVM, etc. • ShiQ burden to learning Packer, rather than learning complex plaSorm-‐specific steps • Can also build Vagrant boxes
- 8. CONSUL • Service discovery, service configura4on, service orchestra4on • Highly available, distributed • Mul4-‐datacenter aware • Discover/configure containers, VMs, physical machines all the same
- 9. TERRAFORM • Launch and combine infrastructure • Amazon, VMware, Azure, OpenStack, and more • Single format to do complex infrastructure management
- 10. VAULT • Secret and cer4ficate management • Built for a modern world: distributed, cloud-‐friendly • Dynamic secrets • Audit pending
- 11. ATLAS Bringing it all together
- 12. How Atlas Works: Configure one holisDc view of applicaDon delivery in days, not years, with infrastructure as code. 12 Atlas
- 13. ATLAS • Built on top of our open source • Adds addi4onal features to each open source project, but running the same binaries • Combines the projects together to provide unified development to produc+on experience • Works for all plaSorms supported by open source! (Hybrid cloud friendly)
- 14. ATLAS • Vagrant box discovery, Vagrant collabora4on • Packer builder, ar4fact storage • Terraform plan/run, collabora4on • Consul UI, aler4ng, alert history
- 15. ATLAS • Governance • Provenance • DevOps friendly • Minimal lock-‐in • Mul4-‐cloud
- 16. ATLAS DEMO Building and launching AWS
- 17. Deployable Ar,fact: AMI { "builders": [{ "type": "amazon-ebs", "access_key": "{{user `aws_access_key`}}", "secret_key": "{{user `aws_secret_key`}}" }], "provisioners": [ { "type": "shell", "inline": [ "sudo apt-get install apache2 -y" ] }], "post-processors": [ { "type": "atlas", "artifact": “mitchellh/cisco-live", "artifact_type": "aws.ami", }] }
- 18. BUILD WITH PACKER $ packer push -name=“mitchellh/cisco-live” template.json Push successful to ‘mitchellh/cisco-live’
- 19. Deploy with Terraform provider "aws" { access_key = "${var.aws_access_key}" secret_key = "${var.aws_secret_key}" region = "us-east-1" } // Packer-built AMI resource "atlas_artifact" "web" { name = “mitchellh/cisco-live" type = "aws.ami" } resource "aws_instance" "web" { instance_type = "t1.micro" ami = "${atlas_artifact.web.metadata_full.region-us-east-1}" security_groups = ["${aws_security_group.allow_all.name}"] # This will create 2 instances count = 2 }
- 20. DEPLOY WITH TERRAFORM $ terraform push -name=‘mitchellh/cisco-live' Push successful to ‘mitchellh/cisco-live’
- 21. SUCCESS! • Automa4c image builds, inventory, history • Automa4c infrastructure change, history • Approval for infrastructure change • ACLs across all of it • Support for all cloud providers the open source supports
- 22. NEXT STEPS… • GitHub integra4on • Consul integra4on for monitoring, service discovery • Using Packer/Terraform with a different cloud service
