Fresh install and test workflow does not work

Using a fresh Xubuntu 18.04 install with the latest versions of Docker CE and docker-compose, and following the instructions on the current branch's github page (https://github.com/nsacyber/WALKOFF/blob/1.0.0-alpha.1/README.md), I am unable to execute a test hello_world workflow. Inspecting the umpire logs in Portainer, I see the following error:

It appears that there is a configuration for 23.202.231.166 that is not documented as needing to be changed during the install process.

Those IPs aren't configured anywhere in our code; that would be what the "redis" hostname resolves to within your walkoff_default network.

The Umpire may start before Redis is ready, in which case it should restart and attempt connecting again, but you may want to try redeploying the stack.

I've mentioned the "bootloader" effort we're working on in a couple of other issues, which aims to smooth out deployment issues such as this one by properly waiting for services to be available instead of just the container coming up.

Thank you for your reply. Can you provide any quick guidance on configuring the walkoff_default network variables/settings?

The walkoff_default network can be configured by editing the top level docker-compose.yml:

WALKOFF/docker-compose.yml

Line 190 in 24a3df8

networks:

Some Docker Compose documentation on configuring networks: https://docs.docker.com/compose/networking/#specify-custom-networks

Assuming a resolution has been reached with new version of Walkoff. Closing this issue.
