worker failed to boot

[ChiliDogDaddyO]

Hello,

I'm getting a "worker failed to boot" message after doing a "docker-compose up". This is occuring both on a Mac M1 Air running Docker version 20.10.8 and on Ubuntu Linux (18.04) also running Docker version 20.10.8

Please advise.

@ChiliDogDaddyO I just checked this, you need to spin up an enterprise search instance and give that URL in config.json for the app to boot up. Because we are initializing the AppSearch Client in main.py.

You can download that at https://www.elastic.co/downloads/enterprise-search/ and follow the installation instructions.

Alternatively, you can create an account at https://cloud.elastic.co/registration.

PS: I'll try to add enterprise search docker containers to docker-compose in this week. (you can find docker containers at https://www.docker.elastic.co/)

excellent, thank you
