Internal Racks and General Enhancements

Internal Racks

You can now set a Rack to Internal mode which will cause all new apps created on that Rack to be created with VPC-only internal load balancers. This mode is great for users building intranet applications where all access will come through VPC peering or VPN gateways.

$ convox rack params set Internal=Yes

Balancer Parameter Removal

The CloudFormation parameters for load balancer configuration are being removed to relieve pressure for large apps running into the 60-parameter limit of CloudFormation. You should specify all load balancer configuration as convox.port labels.

https://convox.com/docs/docker-compose-file/#labels

WARNING: If your app has set these parameters manually without also setting the appropriate labels you will receive an error the next time you deploy asking you to add the labels.

General Enhancements

• #983 Remove load balancer params [@ddollar]
• #989 Api cpu should be capitalized [@beedub]

ELB Idle Timeout and General Enhancements

ELB Timeout Configuration

You can now configure the idle timeout of your load balancers using a label. (#912) [@bobzoller]

web:
  labels:
    - convox.idle.timeout=3600

http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/config-idle-timeout.html

General Enhancements

• #977 allow user env to override docker-compose.yml [@ddollar]
• #979 include port in _URL link var [@ddollar]

Deployment Configuration and General Enhancements

Deployment Configuration

You can now specify the minimum and maximum percentage of containers to have running during rolling deploys using labels in your docker-compose.yml. (#922) [@beedub]

services:
  web:
    build: .
    labels:
      - convox.deployment.minimum=50
      - convox.deployment.maximum=200

WARNING: The DeploymentMinimum and DeploymentMaximum parameters to application stacks have been removed. If you were using these parameters please migrate your application to the labels shown above.

General Enhancements

• Add --no-sync flag to convox start to disable code synchronization (#959) [@awsmsrc]

Autoscale Improvements and General Enhancement

Autoscale Improvements

When calculating the number of instances needed to run your containers we now add one to the total to avoid cases where the instances get packed too close to capacity. (#964) [@ddollar]

The default values for minimum and maximum are 100 and 200 respectively.

General Enhancements

• Add ApiCpu and ApiMemory parameters to the rack to control Rack API resources (@926) [@beedub]
• Use Go 1.6.3 everywhere (#948) [@nathany]
• Remove health params from app stacks (#956) [@beedub]
• Add NAT gateway friendly name during install (#958) [@beedub]
• Add node-workers example to CI (#963) [@MiguelMoll]
• Fix for setting env on an app that has never been deployed (#972) [@ddollar]

Existing VPCs, NAT Gateways, and Infrastructure Improvements

Existing VPCs

You can now create a Rack in an existing VPC during convox install (#946) [@beedub]

$ convox install --existing-vpc vpc-12345678 \
  --vpc-cidr=10.0.0.0/16 --subnet-cidrs=10.0.1.0/24,10.0.2.0/24,10.0.3.0/24

NAT Gateways

This release contains some fixes to move NAT Gateways for Private Racks from a custom CloudFormation resource (Custom::EC2NatGateway) implemented by Convox over to the native AWS::EC2::NatGateway as part of continued efforts to reduce custom handlers in Convox. (#968)

WARNING: The IP addresses of your NAT Gateways will change when you upgrade to this release. If you have whitelisted these IP addresses anywhere you will need to take note of your new IP addresses.

Infrastructure Improvements

We have finalized a massive internal refactoring that greatly simplifies generation of CloudFormation templates. Hats off to @awsmsrc and @MiguelMoll for this massive simplification of Rack! (#939)

• Many custom CloudFormation resources have been removed for their native counterparts
• The code for building images in development and production has been unified
• Multiple fixes for convox start bugs around sub-projects and code sync
• Removed the internal registry when ECR is available
• Rack templates should now boot faster and more reliably thanks to better dependency mapping
• Removed several unused Rack-level CloudFormation parameters
