# Deployment
|
|
|
|
Three ways to run the jump host, in increasing manual effort.
|
|
|
|
## 1. Unified theta-env stack
|
|
|
|
Set in `theta-env/setup.env`:
|
|
|
|
```
|
|
CFG_JUMP_HOST_ENABLED=true
|
|
CFG_JUMP_HOST=jump.example.com
|
|
JUMP_SSH_PORT=2222
|
|
```
|
|
|
|
Re-run `./setup.sh`. It builds the submodule, writes `config/jump-secrets.js`,
|
|
mints the SSO API token, grants the `sshPublicKey` write-ACL to the shared
|
|
`cn=ldapclient` bind account, registers `jump.example.com` in the proxy, and
|
|
seeds a directory entry.
|
|
|
|
Expose SSH: forward the public host's `:22` (or `:2222`) to the container's
|
|
published `JUMP_SSH_PORT`.
|
|
|
|
## 2. Standalone Docker
|
|
|
|
```
|
|
cp secrets.js.example config/jump-secrets.js
|
|
$EDITOR config/jump-secrets.js # LDAP bind (+ sshPublicKey write ACL), SSO url + token
|
|
docker compose up -d --build
|
|
```
|
|
|
|
Host keys persist in the `jump-data` volume. The web UI is on `:3002`; front it
|
|
with your own TLS/proxy.
|
|
|
|
## 3. Bare metal
|
|
|
|
```
|
|
curl -fsSL https://raw.githubusercontent.com/theta42/jump-host/master/ops/install.sh | sudo bash
|
|
sudo $EDITOR /etc/jump-host/secrets.js
|
|
sudo systemctl restart jump-host
|
|
journalctl -u jump-host -f
|
|
```
|
|
|
|
`ops/install.sh` installs Node 22 + Redis, hard-resets the checkout at
|
|
`/opt/theta42/jump-host` to the remote branch, symlinks the systemd unit, and
|
|
runs `npm ci`. Idempotent — re-run to update. Overridable via `REPO_DIR=`,
|
|
`BRANCH=`, `SECRETS_FILE=`.
|
|
|
|
## The LDAP write-ACL (required)
|
|
|
|
The bind account must be able to write the `sshPublicKey` attribute so the jump
|
|
host can inject its key. In the bundled OpenLDAP (`slapd.conf` / `olc`):
|
|
|
|
```
|
|
access to attrs=sshPublicKey
|
|
by dn.exact="cn=ldapclient,ou=people,dc=example,dc=com" write
|
|
by self write
|
|
by * read
|
|
```
|
|
|
|
Without it, key injection fails and every bridge attempt is audited
|
|
`key-inject-failed`.
|
|
|
|
## Listening on port 22
|
|
|
|
Default is 2222 (unprivileged). For 22: set `ssh.listenPort: 22`, and either
|
|
|
|
- systemd: uncomment `AmbientCapabilities=CAP_NET_BIND_SERVICE` in the unit; or
|
|
- Docker: publish `22:22`; or
|
|
- firewall: DNAT `22 → 2222`.
|
|
|
|
## Verifying
|
|
|
|
```
|
|
# from a client whose key is in your LDAP sshPublicKey
|
|
ssh -p 2222 youruid@jump.example.com # TUI picker
|
|
ssh -p 2222 youruid_-_somehost@jump.example.com
|
|
sftp -P 2222 youruid_-_somehost@jump.example.com
|
|
|
|
curl -s http://localhost:3002/health
|
|
```
|
|
|
|
Watch `journalctl -u jump-host -f` (or `docker logs -f jump-host`) and the
|
|
audit log at `/audit` in the web UI.
