The One git commit That Leaks Your Database Password
You hardcoded a password in docker-compose.yml. You committed it. You pushed.
Now it's on GitHub. Forever.
Even if you delete it in the next commit, git history keeps it. Bots scanning public repos find it in minutes. And if it was a production database password, you're already too late.
In this 2-minute explainer:
→ Why hardcoding credentials in YAML is the most expensive Docker mistake new engineers make
→ The .env + .gitignore pattern that keeps secrets out of version control
→ Hardcoded vs .env shown side-by-side: one approach gets you fired, the other keeps your job
→ A Docker Compose quick-reference card you can actually use
→ The Golden Credential Rule: Secrets → .env, .env → .gitignore, never YAML
Built for backend developers, data engineers, and anyone who's ever pushed to a public repo and felt that 3 AM dread.
This wraps the Enqurious Docker series covering layer caching, volumes, networking, and now secrets. Watch the rest on the channel.
