How to store and retrieve my secrets in a linux server? (lemmy.pe1uca.dev)

All guides to deploy using docker mention typing your keys/credentials/secrets into the docker compose file, or use a .env or similar file, I'm wondering how secure is this and if there's a better option.

Also, this has the issue of having to get into the server to manage them, remembering which file has each credential.

Is there a selfhostable secrets manager? I've only found proprietary/paid ones for large infrastructures and I just need it for a couple of my servers/projects.

Perhaps look into hashicorp vault

[–] manitcor@lemmy.intai.tech 4 points 1 year ago

seconded for hashicorp, you can do secrets and env vars while cutting your teeth but you should be on a path to learning and setting up secure secrets vaults.

I wish there was something between hashicorp vault and keepass. I want a nice simple UI that even my family could use with Terraform integration. Anyone know of such a program?

[–] doeknius_gloek@feddit.de 2 points 1 year ago (2 children)

I have no experience with terraform but Bitwarden has an API and CLI, so you might be able to script something with it?

[–] NewDataEngineer@lemmy.world 2 points 1 year ago

Thanks. I knew about bit/vaultwarden but I just looked and I see that there is a Terraform module and the UI looks good.

Thanks.

I was thinking about this, since it'd be using foss, but if no library exists to handle the pass to a script/config file then it'd be maintaining a custom solution which might not be that secure.

Edit: hashicorp's vault is open source, so I'll be giving it a try.

Bitwarden has a CLI that you can script with. Also vaultwarden is the FOSS version.

Just in case you want to try.

There’s also Infisical if you don’t want to run Vault

I personally use Ansible to deploy my .env files to my Docker host. The .env files are encrypted in Ansible Vault and deployed to the server as chmod 400 so only I can access them.

+1 for Ansible Vault

[–] lungdart@lemmy.ca 2 points 1 year ago

The suggestions here are good for production. Over used aws secret manager and hashicorp vault before and both did everything we needed.

I find they're too much firepower for selfhosted, and prefer pass

Simple commandline tool, backed by a gpg encrypted git repo. Perfect for small use cases!
