Using v0.5.3-alpha.3 as recommended in guide results in an error

[danielsbird]

Describe the bug

I am following the Configure and Deploy section of the guides. The following command fails with an error:

docker run -it --rm \
  --network ketoguide \
  -e DSN=$DSN \
  oryd/keto:v0.5.3-alpha.3 \
  migrate sql -e

Here is the error:

Config file not found because "Config File ".keto" Not Found in "[/]""

This is the same error reported in #177 and fixed in #178. I was able to avoid this error by using version 0.5.4-alpha.1 instead of version 0.5.3-alpha.3. The docs should be updated to recommend using 0.5.4-alpha.1 instead of 0.5.3-alpha.3.

Reproducing the bug

Steps to reproduce the behavior:

1. Follow all steps in the Configure and Deploy section of the guides including Run the Ory Keto Service
2. See the above-mentioned error

Expected behavior

I expected that running docker run -it --rm --network ketoguide -e DSN=$DSN oryd/keto:v0.5.3-alpha.3 migrate sql -e would complete without error.

Environment

• Version: v0.5.3-alpha.3
