acrarium - docker issue - communication link failure

[v4g-optimusprime]

I'm trying to setup the acrarium docker by following the steps in setup-guide
https://github.com/F43nd1r/Acrarium/wiki/Setup-guide

I'm able to get it running manually without docker (by running the acrarium jar file -> java -jar acrarium-1.0.0.jar).

Unfortunately, I'm getting stuck with the following issues while try to use docker.

1. SQL exception due to communication link failure
2. Error: creating bean
3. Acrarium exit with code 1 (due to the above errors)

Appreciate any pointers to help resolve these errors.

Environment:
Host: Ubuntu-20.04

network_mode: host prevents you from accessing exposed ports of other containers.

[v4g-optimusprime]

No luck removing the "network_mode: host" from the yml file.
Attaching the debug log FYR..

Not sure how to proceed further.
Let me know if more debug logs would be helpful to root-cause this issue.

Access denied for user 'acrarium'@'172.21.0.3' it's a permission issue now. I haven't tried with mysql 8, so you'll have to investigate yourself why the access is blocked.

[v4g-optimusprime]

mysql-8 works on manual config instead of docker..
not sure why i'm hitting the permission issue

[F43nd1r]

Assuming issue is solved due to no further feedback.
