Today we're proud to announce v1.8 of the Serverless Framework.
v1.8 is yet another special release since we're officially introducing support for Azure via the Serverless Azure functions plugin!
Let's take a deep dive into the highlights of this release.
Highlights of 1.8.0
Note: You can find a complete list of all the updates in the changelog.
Azure functions provider plugin
It finally arrived. The next provider support for the Serverless Framework is here!
We're proud to announce the official Azure functions provider plugin for the Serverless Framework!
You can read the announcement blog post for more information.
Now you're able to write and deploy Azure function applications with the help of the Serverless Framework. Curious what this looks like? Here are some resources to help you get started:

BREAKING - Introducing inline policies
Until now we've created a separate
IamPolicyLambdaExecution resource so that your Lambda functions can interact and execute code appropriately.
PR #2983 updates this behavior so that inline policies are used rather than a separate CloudFormation resource.
This change fixes a bunch of related issues with e.g. VPC setups.
Note: This is a breaking change which affects all users / plugin authors who reference the
IamPolicyLambdaExecution resource since it's removed in v1.8.
Fix file streams during zipping
Recently we've switched from a memory intensive
fs.readFileSync implementation to a
fs.createReadStream implementation for the code zipping (see #3220).
This change reduced the memory footprint by about ~40% which is important when Serverless is used on low power hardware like CI / CD systems or virtual machines.
Unfortunately this fix creates another problem. Old Node versions tend to keep too many files open which results in an error during the zipping process (see #3249).
We've tried different approaches to provide a quick fix for this issue. One was to use the
graceful-fs npm package to wrap the
fs.createReadStream usage. However, those solutions weren't sufficient enough to get into a stable state again.
For v1.8 we decided to switch back to
fs.readFileSync (see #3310) and investigate further.
This is just a temporary fix. We'll work on a long term fix so that a read stream is used again to reduce the memory usage.
Have some ideas about how we can solve this and want to help? Here's the corresponding issue where we capture the progress: #3311!
Fix monitorStack freezing bug
We were finally able to reproduce a nasty bug which caused Serverless deployments to freeze in the
Checking Stack update progress... status.
This problem was introduced due to a clock drift where the time of your local machine is slightly in the future causing AWS server to report incorrect updates about your CloudFormation status.
Luckily we were able to fix this in a way where the status checking is not dependent on your local machines time anymore.
BREAKING - Different displaying of function name in info command
New users coming to the Serverless Framework faced some issues with the different names the function is refered to on their local machine vs. AWS.
We decided to update the
info plugin so that both names are shown. The functions name in
serverless.yml and the name of the deployed function on AWS.
Here's an example output how this looks like:
Service Information service: service stage: dev region: us-east-1 api keys: None endpoints: GET - https://foo.execute-api.us-east-1.amazonaws.com/dev/goodbye functions: hello: service-dev-hello goodbye: service-dev-goodbye
Enhancements & Bug Fixes
This release also fixes some other bugs and introduces some enhancements.
Thanks for reporting bugs and opening issues!
