10.5.3 is a point release for the last major GA release (10.5.0). This release includes:

Features

  1. Added support for RHEL 6 and RHEL 7
  2. Added RightScripts rll/redhat-subscription-register.sh and rll/redhat-subscription-unregister.sh to register and unregister RHEL instances with RedHat Subscription Management Services
  3. Update version of RightScale Network Agent installed for RCA-V instances. Installation of RightScale Network Agent scripts for RCA-V on Linux servers will raise an error if NetworkManager is installed. See Advanced Networking for vSphere for more details.

Fixes

  1. Fix systemd SIGPIPE issue (https://bugs.freedesktop.org/show_bug.cgi?id=84923) by restarting rightlink once process is idle and no longer executing scripts.

Known Limitations
  • When using install-at-boot or custom images on vSphere/Softlayer on Linux, be aware of cloud-init limitations
  • Ensure hypervisor timezone matches instance timezone on Windows or time may be misset. If time is off you may not be able to run operational scripts.

RightScale tested images

The following images were tested by RightScale and known to work with this version of RightLink 10. This list is not intended as a recommendation of these images, it is simply intended as a reference so you can locate known-to-work images and compare with your own images if you are having difficulties.

Known to work means that the following features work: enable a running bare instance using the rightlink.enable.sh or rightlink.enable.ps1 script, reboot the instance, stop and start the instance, support managed login (Linux only), install the RightLink 10 init scripts, and install monitoring (collectd on Linux).

Note: except for VMware the tests for this release use official images prepared by the OS vendor or the cloud vendor. In some cases this leads to failures due to problems with the specific images that can easily be overcome using a custom image.

How-To

Quick Test (Linux Only)

  • From the marketplace import the RightLink 10.5.3 Linux Base ServerTemplate published by RightScale Engineering.
  • Create a Server from the ServerTemplate
  • Select an appropriate MCI and launch. Once the server goes operational, you will see an audit entry with the boot scripts and be able to SSH into the instance using your managed SSH key with your default or custom login name (see Server Login Control for additional information on managed SSH keys)

Adapting the Base ServerTemplate

  • You can clone the base ST and insert a different MCI of your choice, the MCI needs to have the required rs_agent tags (see below)
  • Alternatively, you can create you own ST using your own MCI

  • Standard MCI tags (see RightLink 10: Cloud-init for additional tags for Linux):

    rs_agent:type=right_link_lite
    rs_agent:mime_shellscript=https://rightlink.rightscale.com/rll/10.5.3/rightlink.boot.sh
    (for Install-at-boot on Linux)

  • AWS, Softlayer, Openstack Juno, Google, and RCA-V (vSphere) have been tested; Other images on other clouds with a functioning cloud-init should work, but have not been explicitly tested by RightScale (see above).

  • The Enable Monitoring RightScript will install collectd on Ubuntu and RHEL/CentOS/Compatible OSes, and will use RightLink Monitoring on CoreOS. It could strand on other distros as there may be no support to install collectd via packages. Installation of collectd was verified with CentOS 6, CentOS 7, Ubuntu 12.04, and 14.04 but should work on other versions as well, and use of RightLink Monitoring has been tested with CoreOS stable.

  • Please see RightLink on CoreOS if adapting the Base ServerTemplate for CoreOS.

  • The environment variables available to RightScripts are different, and there are no RS_REBOOT or RS_OS_TYPE variables. Write idempotent scripts using the capabilities of the shell, such as testing for the presence of files. Dispatch based on the presence of tools or file system locations you need instead of a OS type variable.
  • No rs_tag command, instead RightLink 10 can proxy API 1.5 requests and add authentication along the way
  • No built-in Chef support
  • RightScript log output is not sanitized to remove credential values! (Some of them are by the platform but this will change soon.) The sanitization has lots of problems, the only proper solution is for the script writer to ensure sensitive credentials are not output to stdout/stderr!
