Diego v2.38.0

Changes from v2.37.0 to v2.38.0

Significant changes

Component Coordination

• As a application developer I want the system to handle the transfer of staging results larger than 10k to the cloud controller so my applications which generate larger staging results can successfully stage and subsequently start/run on the foundation
  • A recent bump to Buildpack Application Lifecycle can cause task result files to be larger than 10K
    (e.g. java apps). We are bumping the MAX_RESULT_SIZE to 20K to address
    the recent change.

Per-Instance Proxy

• Envoy proxy binary bumped to 4478c1984d17146b1ff78d0babedae2a4752b027

Docker/Image Support

• As a CF app developer, I expect to be able to push Docker apps that are hosted on AWS ECR and that they continue to run when restarted, crashed, or evacuated after the typical AWS ECR credential expiration period
  • App developers who wish to push apps based on images from AWS ECR should set their CF_DOCKER_PASSWORD env variable to the AWS Secret Access Key for the IAM user and pass the AWS Access Key ID for the IAM user as the docker-username in their cf push... command:
    • cf push [appname] --docker-image [repo/ECR-container-image-name] --docker-username [aws-access-key-id]

Component Logging and Metrics

• As a Diego Operator, I can observe the auctioneer logs and see what the auctioneer was trying to place when there was a placement failure so I can better diagnose the root cause of that placement failure
• As a 3rd party network plugin author, I expect my component to be able to tell what containers are internal system containers and don't require networking setup
• Log an error for slow readers on BBS

Test Suites and Tooling

• regenerate-certs.sh under ./rep/cmd/rep/fixtures should regenerate all of the fixture certs
• Flaky Test Crashes with a monitor action when the monitor never succeeds when the process dies with exit code 1 [It] gets marked as crashed (immediately)
• Failing Benchmark BBS Build - mitigate test flakiness
• Failing Benchmark BBS Build - Set the buffer on receiving channel for BBS events
