Transcript

1. Cooking the cloud Managing configuration with Chef, and How Abiquo uses it to provision nodes Ignasi Barrera Senior Software Engineer
2. We will talk about… ¤  The need for configuration management ¤  Quick overview of Chef and its different flavors ¤  What the jclouds-chef project is ¤  How we can combine it with jclouds ¤  How Abiquo integrated Chef inside the platform
3. Configuration management ¤  Centralization of the configuration ¤  Automation in large infrastructures ¤  Ease of maintenance ¤  Automatic provisioning
4. How does it look like in Chef ¤  Cookbooks ¤  Recipes ¤  Ruby scripts ¤  Templates ¤  Configuration attributes ¤  Nodes ¤  Maintain the configuration of each node ¤  Databags
5. ChefContext chefContext = ContextBuilder.newBuilder( “chef|hostedchef|privatechef”) .credentials(client, certificate) .build(); chefContext.getApi(); // Returns the typed API Pick your favorite flavor ¤  Community Chef (Open source) ¤  Hosted Chef (PaaS, free limited account) ¤  Private Chef (Opscode Chef inside the firewall)
6. The Chef service ¤  Stores bootstrap configuration The configuration is stored in the Chef Server and is accessible for jclouds and the nodes ¤  Generates the bootstrap script The script can be executed with the ComputeService updateBootstrapConfigForGroup(runlist, config, group); bootstrap = createBootstrapScriptForGroup(group); compute.runScriptOnNode(id, bootstrap);
7. The Abiquo approach ¤  Software provisioning should be a simple process ¤  Users should be able to provision and configure software when they need it ¤  Each tenant should be able to configure custom software packages
8. Tenant management ¤  Each tenant can configure the access to a custom Chef server ¤  The tenant will be able to manage the cookbooks and recipes in the Chef server
9. Node configuration ¤  The list of recipes available in the tenant’s Chef server is presented to the user ¤  The user can select which recipes and roles will be applied to the node ¤  Supports live configuration!
