Unreleased

Any changes which are committed, but not yet present in a released version, should appear here.

  • Yo now has support for multiple OCI regions!

    • Previously, if you wanted to run yo against another OCI region, you needed to edit your config, run yo cache-clean, and then run your commands.

    • Now, Yo allows you to store configuration for several OCI regions into your config. You set a default region in your config file, but you can override it with the YO_REGION environment variable, or yo -r REGION on the command line.

    • Please see the documentation for a migration guide: https://oracle.github.io/yo/guide/region.html#migrating-yo-ini-to-multi-region-support

  • Switched Yo’s default setup dialog to use oci setup keys. Updated documentation accordingly.

1.6.0 - Wed, Apr 17, 2024

New Features:

  • The yo list command now has a completely configurable table.

    • Columns may be specified as a list in the config file (list_columns)

    • An alternative list may be specified via yo list -C a,b,c

    • Columns can be added to the end of the table with yo list -x Column

  • The yo list command includes a new column, ResourceType, which corresponds to the value of the Oracle-Recommended-Tags.ResourceType tag.

1.5.1 - Tue, Apr 9, 2024

Another tiny release, which I configure a “bugfix release”.

Fixes:

  • Fixed a crash with yo nmi

  • Added --ad option to yo launch which was a bit of an oversight

1.5.0 - Mon, Feb 5, 2024

This is a very tiny release with just three changes.

New Features:

  • The “yo attach” and “yo detach” commands now work with boot volumes.

Fixes:

  • Allow “yo teardown” operation to occur in states other than RUNNING. Specifically, it should be possible to teardown STOPPED instances. The operation isn’t permitted in TERMINATED or TERMINATING states.

  • Respect the termination protection option for “yo teardown”. Previously, “yo teardown” would happily terminate a protected instance.

1.4.0 - Fri, Dec 15, 2023

This version of Yo comes with some major improvements.

New Features:

  • Two new instance actions are added: “teardown” and “rebuild”. The teardown operation terminates the instance, but preserves the boot volume, and attaches some metadata to the instance so that Yo will know how to rebuild it the way it was. The “rebuild” operation does exactly that.

    • This operation might be preferred instead of “stop” and “start” in cases where your tenancy is encountering service limits. Stopped instances still count toward your service limits, while terminated instances do not.

    • Please note that for now, “teardown” cannot remember what block volumes were attached to your instance, and so “rebuild” will not reattach block volumes (aside from the boot volume, of course). This feature could be added if there is demand for it.

  • You may now specify a custom username for your instances! This can be specified in your instance profile configuration, or on the yo launch command line. Yo will automatically keep track of the username for each instance using a tag, so you don’t need to remember which you chose. So the existing yo ssh commands will work regardless of your username choice.

  • You may now specify a boot volume to launch an instance from. If you terminated a volume with (--preserve-root), then you can launch an instance from the same boot volume. This operation is similar to “rebuild”, except that you must manually specify the instance shape, name, etc.

  • There is a new command, yo copy-id, which wraps ssh-copy-id. Use it to copy SSH keys over to an instance. For the most part, you shouldn’t need this because Yo passes your key in anyway, but it could be useful to add more keys.

Changes:

  • The default configuration of Yo now specifies the VM.Standard.x86.Generic shape with 1 CPU and 8 GiB of memory.

  • The yo list command no longer shows instances in TERMINATING state.

  • The yo -h help output is now organized into logical categories with well-written command summaries.

  • Documentation for each Yo sub-command is now automatically generated to match the CLI.

  • Sub-commands are now permitted: commands like yo volume-list are now yo volume list. However, the old spellings are still permitted, as we don’t want to break anybody’s muscle memory.

  • Yo’s command aliasing is now improved. Prior to this release, Yo used shortest-prefix aliasing, but if you wanted to specify your own alias mapping, then shortest-prefix mappings were disabled. This limitation has now been removed. If you specify custom aliases, then Yo will use them, and will still create shortest-prefix aliases for the rest of the commands.

Fixes:

  • Fixes an error due to a missing minimum version of the rich library.

  • If you have provided memory / cpu configurations in an instance profile, but you then override the profile with a non-flex shape, Yo used to raise an error. However, this isn’t a very helpful error: it’s clear the user wants the non-flex shape and forgot about the default flex configuration. So we’ve removed this unnecessary error.

1.3.1 - Wed, Sept 6, 2023

Fixes:

  • Fix FileExistsError on Windows.

1.3.0 - Fri, Sept 1, 2023

Changes:

  • The look & feel of Yo has been updated a bit. Progress bars have been removed in favor of spinners, since we can’t accurately predict progress most of the time anyway. The spinners also show the time elapsed even after completion, so that you know how long Yo spent waiting for each action. Most of the printouts now also include a timestamp.

  • Yo now catches Ctrl-C gracefully and exits without a traceback.

  • The creator_tags configuration option is added. This configuration is related to how Yo tracks instances which you’ve created. If Yo is already working for you, there’s no need to care about it.

Fixes:

  • Fixed some bugs related to parsing information in InstanceProfile.

  • Fixed a very rare bug related to the automatic update checking.

  • Fixed a bug related to the default configuration of memory for flexible CPU instances.

1.2.0 - Wed, Aug 9, 2023

New features:

  • Add yo launch --wait-ssh, which waits for SSH to come up, but doesn’t actually connect you to SSH.

  • Add yo list --ip, which adds an IP address column for yo list.

  • Improved the speed of IP address lookups, when loading IPs for several instances at a time (e.g. yo list --ip or yo ip).

  • Add yo list --all, which prints info about all instances in the compartment, not just your own. Yo still is not capable of managing these instances, it is just an informational view.

  • The short argument -E is now usable in place of --exact-name.

  • The --exact-name -E arguments are now added to the block volume management commands. They apply both to the name of the instance, and the block volume.

  • A new configuration, exact_name, is added to the yo.ini. This has the effect of implying --exact-name on every command without you needing to type it.

  • A new argument, --no-exact-name, allows you to override exact_name = true in your configuration on a case-by-case basis.

  • A new configuration, resource_filtering, is added to yo.ini. This allows Yo to view and manage all resources in your compartment, not just the ones you’ve created. This is not a recommended configuration, please be careful when using this.

  • During yo list, Yo will now automatically check for newer versions in the background. If it finds a newer version, it will print a notice. As a default, the version checks are a minimum of 6 hours apart, but this can be configured with the config check_for_update_every. Setting the configuration to 0 will disable the feature.

Changes:

  • yo list now sorts your instances by creation time, rather than the default (presumably undefined) ordering returned by the API.

Fixes:

  • A rare issue with concurrent accesses to the Yo cache has been resolved. Cache updates are now atomic.

  • Yo now refreshes the instance list prior to running the start, stop, reboot, terminate commands. This ensures that it is operating on the correct set of instances, avoiding rare but important caching bugs.

  • Improved error messages that occur when looking up an instance by name, so that the message includes the actual instance that Yo tried to search for (as impacted by --exact-name).

  • Fixed a compatibility issue with Windows due to the use of “fchmod()”

  • Fixed a silly bug in which yo cache-clean failed if the cache file does not exist.

1.1.0 - Tue, July 18, 2023

  • Yo now adds the freeform tag: {"yo-created-by": "your.email@example.com"} to every instance it launches.

    • In cases where the tenancy does not automatically add a Oracle-Tags.CreatedBy tag, we fall back to the above freeform tag to identify instances launched by the current Yo user.

    • If the Oracle-Tags.CreatedBy tag is not present on instances in your tenancy, Yo prints a loud warning with more information. You can silence this warning by setting silence_automatic_tag_warning = true in the config.

  • Yo can now handle instances of Oracle-Tags.CreatedBy which contain a prefix ending in a slash (/) before the email address.

1.0.4 - Mon, June 5, 2023

  • Bugfix release for the extension API changes in 1.0.3.

1.0.3 - Fri, June 2, 2023

  • A minor change to an internal extension API, which was omitted in 1.0.2.

1.0.2 - Fri, June 2, 2023

  • The SSH options added in 1.0.1 have been updated to improve compatibility with older SSH versions. If you encountered the following error during a yo console, then it’s likely this fix will resolve your issue:

    command-line: line 0: Bad configuration option: pubkeyacceptedalgorithms

  • Yo no longer crashes when encountering an instance with multiple VNIC attachments. Instead, it just warns that it is blindly taking the first VNIC. We’ll need more user feedback to inform the correct behavior.

1.0.1 - Tue, May 9, 2023

  • Yo is now located at https://github.com/oracle/yo, and documentation is now located at https://oracle.github.io/yo/. This will be its permanent home, please update any bookmarks.

  • Some SSH options have been added for the Instance Console Connection, in order to make it work on newer OpenSSH versions.

  • The documentation has been improved in a few places: namely regarding SSH configuration.

1.0.0 - Tue, April 18, 2023

This is the initial public release of Yo! It’s the culmination of 26 minor internal releases over 2.5 years, and we’re pleased to present it to the public.
