AppScale 3.3 Release

[William Friedman]

We are excited to announce the new release of AppScale. AppScale 3.3 strengthens and perfects the new features introduced in 3.2, and the main theme for this release has been to improve the cloudability (new minted term just for this blog post) of AppScale. We added support for Ubuntu Xenial,  improved our build scripts, expanded regression testing, and tuned our auto scaling policies to improve responsiveness.

 

Here are the main changes for this new release:

• Added support for Ubuntu Xenial
• Improved auto and manual scaling capabilities
• Added performance profiling for internal services
• Added support for Google Admin API
• Published in Azure Marketplace, thus adding to the long list of single-click deployments

 As usual you can find the detailed list of changes in Github.

Dear William Friedman,

When I tried to upgrade by running "appscale upgrade", I got the following error.

"3.3.1" not recognized: use --tag to specify tag to upgrade to.

Could you give me some information on fixing this problem?

Best regards!

Hello Peak,

how did you get AppScale installed the first time around, did you use
one of our images? Did you start from a release? Are you connected to
internet (that is can you see github from the appscale machine)?

cheers

Hi, Graziano,

The current installation is using the official image provided by appscale proxy in China.

The version is 2.9.

During the upgrading, it says the git has latest version.

Best regards!

Your original error looks like git was not able to query the available tags from GitHub to verify that 3.3.0 is a valid tag. If the appscale upgrade command is giving you trouble, you can still upgrade the deployment manually.

To do so, first make sure AppScale is not running. Then run `git checkout 3.3.0` and `bash debian/appscale_build.sh` on every machine in the deployment. You'll also need to do that for the appscale-tools repository. Afterwards, you'll need to run the datastore upgrade script since the data layout changed with AppScale 3.0. As long as it succeeds, you'll only need to run it once:

python scripts/upgrade.py\

  --keyname <your keyname, you can find this in your AppScalefile>\

  --log-postfix 1\

  --db-master <IP address of your first database machine>\

  --zookeeper <a list of your ZooKeeper IP addresses separated by spaces>\

  --database <a list of all the database IP addresses separated by spaces>\

  --replication <a number specifying your replication factor>

After that script completes, check the contents of /var/log/appscale/upgrade-script-1.log to verify that it completed successfully. You should be able to run `appscale up` after that.
