agent: Continuous recording: panic: runtime error: invalid memory address or nil pointer dereference

Hello,

I am trying enable “Continuous recording” but no success. Every time I enable container crash. I am using docker +docker compose instead of kubernetes.

docker-compose.yml

did that help? @nurio-felix

@cedricve Sorry for delay. Yes, I created persistent volume and now is working fine. Thanks for help guys.

If you want pick docker-compose.yml stuff that I placed here for people that do not want deploy using kubernettes, you can add also to documentation.

docker-compose.yml

wonderful! we have been looking into your approach, and actually like how you like to avoid kubernetes. Would you consider to write an medium/blog article to discuss your deployment? Might be really interesting for users, to quickly bootup some agents + a Kerberos Vault.

Yes I can write docker + docker compose implementation. I avoid kubernetes because actually I am using this for small scale in my home surveillance, so I think is more easy to setup.

For standart I think in their homes people will choose docker compose. It is possible making kerberos (agent + vault + storage) home surveillance using Port forwarding (80,443) in Router to Virtual Machine that can be created using Virtual Box with or without vaild domain name.

With kerberos is possible avoid NAS hardware, replaced by Minio, so I think is better in costs, one Virtual Machine with 2 Cores and 4GB RAM can make all work.
