Getting started with the Fog cloud services library. Presented at the SDRuby monthly meeting on November 3, 2011

1. Fog Ruby Cloud Services Library
2. github.com/fog/fog fog.io @fog
3. APIs Hurt
4. 1. Search for existing, often shoddy library
5. 2. DIY Wrapper
6. 3. New vendor comes along that does your laundry too!
7. 4. Sad face :(
8. Amazon EC2 Amazon S3 Zerigo DNS RS Files RS Servers Amazon Cloudfront Amazon Route 53 Dynect DNS DNSimple Amazon RDS Linode Google Storage
9. Cross Service Compatibility
10. gem install fog
11. require 'fog'
12. Cloud Storage
13. s3 = Fog::Storage.new( provider: "AWS", aws_access_key_id: "KEY", aws_secret_access_key: "SECRET" ) gg = Fog::Storage.new( provider: "Google", google_storage_access_key_id: "KEY", google_storage_secret_access_key: "SECRET" ) rs = Fog::Storage.new( provider: "Rackspace", rackspace_api_key: "KEY", rackspace_auth_url: "URL", rackspace_username: "USERNAME" ) s3.put_object(bucket_name, object_name, data, options = {}) gg.put_object(bucket_name, object_name, data, options = {}) rs.put_object(container, object_name, data, options = {})
14. s3.put_object(bucket_name, object_name, data, options = {}) gg.put_object(bucket_name, object_name, data, options = {}) rs.put_object(container, object_name, data, options = {}) Consistency Provider Flexibility
15. Cloud Servers
16. ec2 = Fog::Compute.new( provider: "AWS", aws_access_key_id: "KEY", aws_secret_access_key: "SECRET" ) rsc = Fog::Compute.new( provider: "Rackspace", rackspace_api_key: "KEY", rackspace_username: "SECRET" ) ec2.servers.create( flavor_id: "c1.medium", image_id: "ami-6936fb00", # Ubuntu 10.04 LTS key_name: "mykeyname", groups: ["default"], ) rsc.servers.create( flavor_id: 5, # 4GB Memory image_id: 49, # Ubuntu 10.04 LTS name: 'my_server_name' )
17. DNS
18. z = Fog::DNS::Zerigo.new( zerigo_email: "email", zerigo_token: "secret", scheme: "https", port: 443 ) zone_id = z.create_zone("bensie.com", 14400, "pri_sec") .body["id"] z.create_host(zone_id, "CNAME", "ghs.google.com", hostname: "mail", ttl: 14400 )
19. AWS Management Console RS Cloud Control Panel • Multi-step wizards • Missing features • Slow • One account at a time
20. AWS Management Console
21. rds = Fog::AWS::RDS.new( aws_access_key_id: "KEY", aws_secret_access_key: "SECRET" ) rds.create_db_instance("my-db-instance" "AllocatedStorage" => 50, "AutoMinorVersionUpgrade" => false, "BackupRetentionPeriod" => 3, "DBInstanceClass" => "db.m1.large", "DBParameterGroupName" => "utf8", "Engine" => "mysql", "EngineVersion" => "5.5.12", "MasterUsername" => "username", "MasterUserPassword" => "password", "MultiAZ" => true )
22. rds = Fog::AWS::RDS.new( aws_access_key_id: "KEY", aws_secret_access_key: "SECRET" ) rds.create_db_parameter_group( "utf8", "mysql5.5", "utf8" ) rds.modify_db_parameter_group("utf8", [ { "ParameterName" => "character_set_server", "ParameterValue" => "utf8", "ApplyMethod" => "immediate" }, { "ParameterName" => "collation_server", "ParameterValue" => "utf8_general_ci", "ApplyMethod" => "immediate" } ] )
23. elb = Fog::AWS::ELB.new( aws_access_key_id: "KEY", aws_secret_access_key: "SECRET" ) load_balancers = elb.describe_load_balancers .body["DescribeLoadBalancersResult"] ["LoadBalancerDescriptions"] load_balancers.each do |lb| elb.register_instances_with_load_balancer( ["i-3dcba453", "i-37cba459"], lb["LoadBalancerName"] ) end
