SSH Reverse Proxy
-L Option
Adding an OCI VNIC
Simply attaching a VNIC does not make the OS pick it up right away.
Managing Linux SSH Keys
A well-configured ~/.ssh/config file can cleanly resolve most SSH connection problems.
IMAP Cron-Job Parsing Bot
A Python script that automatically fetches and parses the latest email from an IMAP server. Running it periodically as a cron job automates email reception.
Automated GitHub Actions Docker Deployment
A workflow that automatically builds a Docker image with GitHub Actions and pushes it to DockerHub.
Linux Swap Creation Script
Deploying NestJS with Docker
A Dockerfile that containerizes a NestJS application with a Docker multi-stage build. Separating the build and runtime stages minimizes image size.
Connecting Without a Wallet
Oracle Autonomous Database uses mTLS by default, which authenticates by downloading an electronic wallet file and installing it on the client. Connecting without managing a wallet requires switching to TLS-only mode. I could not find Korean documentation explaining this for the combination of macOS and DBeaver, so I wrote it down here.
