What kejilion.sh Actually Does
kejilion.sh is a 40,000-line interactive shell menu that consolidates system monitoring, Docker management, LDNMP stack deployment, and network diagnostics into a single curl-pipe-bash workflow. It's designed for operators managing multiple Linux VPS instances who need repeatable setup without memorizing 50 different CLI flags.
One-line install:
curl -sL kejilion.sh | bash
After first run, you can alias it to k for instant access.
What I Tested
When integrating kejilion.sh into our agent relay infrastructure failover pipeline, I needed to verify three things:
- Docker container management reliability — our coding agents (Cline, Aider, Roo) hit HTTP 429 rate limits during peak hours; we route them through a B-Lost multi-model gateway running in Docker. If the container management layer has race conditions or leaves orphaned volumes, the failover breaks.
- LDNMP stack safety — does the script check for existing Nginx/MySQL processes before attempting install? Our gateway already runs Caddy on port 443.
- Menu timeout behavior — what happens if you launch the interactive menu over SSH and the connection drops mid-operation?
Key Findings
Docker management is solid but verbose. The script wraps standard docker and docker-compose commands with safety checks (it won't nuke a running container without confirmation). However, the menu doesn't expose docker-compose project names directly, so you'll need to docker ps --filter 'label=com.docker.compose.project' to audit what the script actually deployed.
LDNMP collision detection exists but isn't foolproof. The script checks for port 80/443 occupancy before installing Nginx, but it uses netstat or ss — if your existing reverse proxy binds to a Unix socket or non-standard port, the check passes and you get a silent conflict. Always run ss -tlnp | grep ':80\|:443' before triggering the LDNMP module.
SSH disconnect during an apt/yum transaction leaves partial state. The script doesn't use screen or tmux internally, so if your connection drops during a package install, you'll need to manually run dpkg --configure -a (Debian/Ubuntu) or yum-complete-transaction (CentOS/RHEL) before re-running the menu.
Integration Pattern
For automated agent relay failover, we skip the interactive menu and call the underlying functions directly:
# Extract the Docker management function
curl -sL kejilion.sh | sed -n '/^docker_manager()/,/^}/p' > /tmp/docker_helper.sh
source /tmp/docker_helper.sh
This gives us programmatic access to the Docker safety checks without blocking on user input.
When our coding agents hit upstream 429 errors or 504 timeouts, the failover daemon spins up a backup gateway container using kejilion.sh's Docker primitives, then updates the agent's --api-base to point at the new endpoint. Round-trip recovery is under 8 seconds.
When Not to Use It
If you're already using Ansible, Terraform, or NixOS declarative configs, kejilion.sh adds an imperative layer that fights your existing state management. It's best for bare-metal VPS instances where you need quick diagnostics and don't want to maintain a full IaC stack.
The script also assumes root access and modifies global firewall rules (iptables, ufw, firewalld) without version control, so it's incompatible with compliance environments that require audit trails for every config change.
