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.
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
