Changelog

Today we updated our Xcode 9.0 beta image to Xcode 9.0 beta 2 with the latest 10.2 simulators. To start using it, add the following to your circle.yml:

  xcode:
    version: "9.0"

This image tag will be upgraded automatically when new betas are released by Apple, until the final release of Xcode 9.

A few weeks ago we started downloading CocoaPods specs from S3 instead of Git in projects that use our iOS inference. It is now also possible to download the specs from S3 in projects with manual configuration.

Please check out this Discuss post for an example of downloading specs from S3 via a circle.yml command.

We have released patches to our AMIs and other infrastructure to address CVE-2016-8655. We recommend all CircleCI Enterprise installations follow the instructions below to update both their Services box and their Builder fleet.

If you have any questions or difficulties please contact enterprise-support@circleci.com.

Update the Services box:

1. As always, ensure your data is backed up.
2. Shut down CircleCI in the Replicated console (or via the CLI).
3. Update the kernel using the provided install_kernel_master function below.
4. Restart the machine.

#!/bin/bash
function install_kernel_master() {
    echo '>>> Installing Kernel'
    apt-get update
    apt-get install linux-image-3.13.0-105-generic linux-headers-3.13.0-105-generic linux-image-extra-3.13.0-105-generic
    apt-cache policy linux-image-3.13.0-105-generic linux-headers-3.13.0-105-generic linux-image-extra-3.13.0-105-generic
}

Update the Builder fleet:

For the builder fleet, update the Launch Configuration to use the updated AMI from the list below:

• ap-northeast-1 = “ami-07f09d60”
• ap-northeast-2 = “ami-90588ffe”
• ap-southeast-1 = “ami-4f54f82c”
• ap-southeast-2 = “ami-040c3467”
• eu-central-1 = “ami-3465a35b”
• eu-west-1 = “ami-d70421a4”
• sa-east-1 = “ami-2e6bf242”
• us-east-1 = “ami-e68f89f1”
• us-west-1 = “ami-901c4af0”
• us-west-2 = “ami-0c57fc6c”

If you are using our Terraform scripts, you can download the new script https://github.com/circleci/enterprise-setup/blob/master/circleci.tf and run terraform apply. We’ve already updated the scripts to include the new AMIs, so terraform should launch new builders automatically with the patched version, and cycle your fleet.

If you are using a non-AWS environment, use the same method to patch your builders you used to patch the Services box.

If any of the above does not apply to your environment, or you encounter issues with your upgrades please contact: enterprise-support@circleci.com.

NOTE: The following AMIs are not maintained by CircleCI, but contain a patched version of stock ubuntu.

• gov-west-1 = “ami-34df6755”
• cn-north-1 = “ami-92f622ff”

New Feature: The maximum size of files that you can upload for caching during builds has been fixed to 5G. The size is now bumped 20G by default on CircleCI Enterprise and customers can also override the default value to even larger size.

To override the default value, you need to run the following in a REPL of Service Box.

(settings/set {:max-file-cache-bytes <max-size-by-bytes>})

To unset the overridden value and use default, run the following.

(settings/unset! [:max-file-cache-bytes])

This release fixes a bug in the URL structure used to serve build artifacts.

The artifact URL format was recently changed to handle security concerns related to CircleCI’s hosted offering. The security concerns do not affect CircleCI Enterprise customers, but the change caused issues fetching build artifacts in CircleCI Enterprise installations. This release reverts the CircleCI Enterprise artifact format and resolves the issue.

Please make sure that you are using the latest provision-builder.sh and init-builder-0.2.sh before you upgrade to this release:

https://s3.amazonaws.com/circleci-enterprise/provision-builder.sh

https://s3.amazonaws.com/circleci-enterprise/init-builder-0.2.sh

As part of this release we’re changing the behavior of artifacts to only serve an allowed set of content-types. This means we won’t serve .html files as text/html. This is a security risk on CircleCI Enterprise since artifacts are served on the same domain as the rest of the site – as a result, any user or malicious code used as part of your build can push a specially-crafted artifact and gain control of another user’s account.

If this is an issue, you can override this behavior by setting “Serve artifacts with unsafe content-types” in the admin console. We don’t recommend this, but we’re providing it for backwards compatibility.

This release also includes some changes to container networking. Containers now each use a /24 in the subnet 172.16.1.0/16 by default.

If this conflicts with your private network, or if you were editing lxc-net manually in order to fix a prior conflict, you can now use CIRCLE_CONTAINERS_SUBNET and CIRCLE_CONTAINERS_SUBNET_NETMASK_LENGTH on the builders to configure those.
