Welcome to the Cloud 66 Changelog. Please take a quick look at the latest changes that have gone out this week!
Ruby v2.6.0 Support
We now support Ruby v2.6.0 on our Ruby/Rack stacks!
Read the release notes.
Ps. Make sure your app (and Gems) work with Ruby v2.6.0 before upgrading! Gem changes to support new versions of Ruby can sometimes take a while to settle!
Graceful ENV Var Updates for Rails Stacks
Pleased to announce a change in behaviour with regards to the application of ENV vars to Rails stacks.
Previously; when you update ENV vars on a stack, we would loop through your servers, and update their ENV vars appropriately. When updating ENV vars, affected processes themselves sometimes need to be restarted.
Now, to minimise downtime, we will batch your traffic bearing servers (web servers behind your load balancers) into 25% size groups, and remove those servers from your loadbalancers, update them, then add them back on.
This means quick rollout of ENV var updates; but still keeps your applications alive!
For more information, visit our help page.
Documentation for Maestro V1 (CSv1) will soon be deprecated
We have merged and consolidated our documentation for versions 1 & 2 of Maestro into a single set that is available here.
As of next week, we will be redirecting all URLs from the Version 1 docs (AKA “Docker legacy”, CSv1) to the equivalent pages in the consolidated doc set. If you have any concerns or questions please chat to us on Slack or via email.
Rails Stack Controlling Node Version
You can now control the node version that is installed! We automatically install Node when we set up your Rack/Rails stack servers. With the surge in popularity of webpack, customers have been asking for control over the specific Node version, and they can now do that through the use of their manifest!
rails:
configuration:
node_version: "6" # will install latest v6.x.x
node_version: "6.14" # will install latest v6.14.x
node_version: "6.14.4" # will install specific v6.14.4
Note: to apply Node version changes you need to update your manifest in your code, then deploy-with-options selecting the "Apply Ruby/Node upgrades" option.
Help on this is available here.
