How to install zbctl


#1

Heya.

The docs mention to create a default topic using the zbctl command. However, there is no information easy to find anywhere how to get the zbctl to work on Windows. Can you shed some light on how to install it? Why is it not part of the distro? Should it be probably explained in the docs? Especially since currently it is a must to have in order to create the required default-topic.

Thanks
Bernd

PS: I still vote to remove the need to create the default-topic - it would increase the get started experience BIG TIME.

Hi,

zbctl will be in the distro starting with the next release, see https://github.com/zeebe-io/zeebe/issues/544

Find the latest zbctl release here: https://github.com/zeebe-io/zbc-go/releases. Installation instructions: unzip and run.

Cheers,
Thorben

By the way - if I run the zbctl and don’t have a broker running the rror message leaves room for improvement :slight_smile: Let me know if I shall create an issue for it.

I changed it to five characters now :slight_smile:

Sure, please go ahead here: https://github.com/zeebe-io/zbc-go/issues. Maybe this is already better in the current snapshots, but then we can still simply close the issue.

Just a quick heads up, zbctl moved to an own repository https://github.com/zeebe-io/zbctl. So the release will be published in the new repository and if you have issues specific to the CLI please create tickets in the zbctl repo. We plan to publish a new release of zbctl next week.
