# Podman

Run the Optimum Gateway with rootless Podman. Same binary and config as
[Quick Start (Docker)](01_quick_start.md) — this page only covers where
Podman's defaults differ from Docker's and will silently break the gateway
if you don't account for them.

## Why this page exists: rootless networking

Docker's default bridge network and Podman's default rootless network are
**not the same thing**. Rootless Podman without `--network=host` runs the
container behind `slirp4netns`/`pasta` — a user-mode NAT. The gateway inside
that namespace detects a private, non-routable address, advertises *that* to
the Optimum bootstrap registry, registers as "reachable," and then silently
receives **no inbound mump2p peers** — publishing port `33213` on the Podman
CLI does not fix this, because the gateway never advertises the address that
port mapping makes reachable.

This is the same underlying problem the [Kubernetes guide](05_kubernetes.md#networking-why-hostnetwork-is-required)
documents for `hostNetwork` — the gateway has no announce-address override.
The fix here is the same shape: run the container in the host's network
namespace.

```sh
--network=host
```

With `--network=host` there is nothing to publish — the container simply
listens on the host's ports directly. Do not combine `-p`/`--publish` with
`--network=host`; Podman will ignore or reject it.

github.com/gofiber/fiber/v3 v3.4.0 App.Listen ":port" bind all interfaces documentation

💡 Result:

To bind a Fiber v3 application to all network interfaces (often referred to as 0.0.0.0 or wildcard binding), you should pass "0.0.0.0:" followed by your port number to the App.Listen method [1][2][3]. For example, to listen on all interfaces on port 3000: app.Listen("0.0.0.0:3000") In Fiber, passing only a colon and a port (e.g., ":3000") typically binds to all available interfaces by default because it instructs the underlying Go net.Listen call to bind to all interfaces [1][3][4]. However, explicitly using "0.0.0.0:3000" is the standard and unambiguous way to ensure the application listens on all IPv4 interfaces [1][5]. Important notes: 1. Interface Behavior: Binding to "0.0.0.0" makes your application accessible from other machines on the network, whereas binding to "127.0.0.1" (or "localhost") restricts access to the local machine only [5]. 2. Startup Messages: Be aware that in some older versions or configurations, Fiber's terminal startup banner may display "127.0.0.1" even when the application is correctly bound to "0.0.0.0" [5]. This is a display behavior intended to provide a clickable link for local development and does not reflect the actual network binding, which can be verified using system tools like netstat or lsof [5]. 3. ListenConfig: If you require advanced configuration (such as enabling preforking or specific network settings), you can pass a fiber.ListenConfig as the second argument [6][1][3]. app.Listen("0.0.0.0:3000", fiber.ListenConfig{ EnablePrefork: true, })

Citations:

Keep telemetry port 48123 local.

cmd/main.go passes :48123 to routes.NewAppRouter, which passes it to Fiber Listen; this wildcard bind can expose /health, /metrics, and /api/v1/self_info on every host interface under --network=host. Bind telemetry to 127.0.0.1 or document and enforce a firewall rule before release.

> **Security note:** the gateway's telemetry HTTP server (`/health`,
> `/metrics`, `/api/v1/self_info` on port 48123) listens on all interfaces,
> not just localhost. With `--network=host` that means it's reachable from
> the network the host is on — the public internet, if the host has a
> public IP with no firewall in front. Restrict port 48123 with a host
> firewall (e.g. `ufw deny 48123` / only allow from your monitoring
> source) unless you specifically want it externally reachable.

## Requirements

* **Podman 4.4+** (rootless)
* A host with a **public IP**
* Inbound **TCP 33213** open to that host from the internet — the Optimum
mump2p port; the gateway is unusable without it
* The CL client able to reach the gateway on **TCP 33212**
* Outbound HTTPS to `bootstrap.getoptimum.io` and `auth.getoptimum.io`
* SELinux-enforcing hosts (Fedora, RHEL, CentOS Stream): see the volume note below

## Run

```sh
mkdir -p config data/libp2p data/mump2p
# fill in config/app_conf.yml — see Quick Start (Docker) for the minimal example
```

```sh
podman run --name optimum-gateway -d \
--network=host \
-e OPT_API_KEY=$OPT_API_KEY \
-v $(pwd)/config:/app/config:Z,ro \
-v $(pwd)/data/libp2p:/tmp/libp2p:Z \
-v $(pwd)/data/mump2p:/tmp/mump2p:Z \
getoptimum/gateway:v1.1.1 \
-config=/app/config/app_conf.yml
```

### The `:Z` suffix

On SELinux-enforcing hosts, a bind mount without a label suffix fails with a
generic `permission denied` — nothing in the gateway's own logs points at
SELinux. `:Z` applies a private, container-specific label to the directory
so **only this container** can access it. Use `:z` (lowercase) instead only
if the same host directory must be shared with another container running at
the same time. On non-SELinux hosts (Debian, Ubuntu without SELinux) the
suffix is accepted and ignored — safe to leave in either way.

If you see `permission denied` on the identity or config directories despite
the `:Z` suffix, confirm the host directory is owned by your user, not root:

```sh
podman unshare chown -R $(id -u):$(id -g) config data/libp2p data/mump2p
```

> Persist `data/libp2p` and `data/mump2p` across restarts — as with Docker,
> without them the gateway's peer ID changes every run and your CL client's
> configured multiaddr goes stale.

## Verify

Same checks as Docker, since `--network=host` means the ports are just the
host's ports:

```sh
curl -s http://localhost:48123/health | jq
curl -s http://localhost:48123/api/v1/self_info | jq '{peer_id, multiaddrs: .libp2p.multiaddrs}'
```

`multiaddrs` must show a **public** IP, not `10.x`/`172.x`/`192.168.x`. A
private-only address here means `--network=host` was dropped somewhere, or
the host itself has no public interface.

```sh
podman logs optimum-gateway
```

## Connect CL Client

Identical to [Quick Start — Connect CL Client](01_quick_start.md#connect-cl-client):
get `peer_id` and a reachable multiaddr from `self_info`, then use the
Prysm/Teku/Lighthouse/Nimbus/Lodestar flags documented there. Nothing about
peering changes with Podman — only the container networking above does.

## Production: systemd Quadlet

For a restart-on-boot, restart-on-crash deployment, use a
[Quadlet](https://docs.podman.io/en/latest/markdown/podman-systemd.unit.5.html)
unit instead of a bare `podman run`. Quadlet generates a systemd service from
a declarative `.container` file — the Podman equivalent of Compose's
`restart: unless-stopped`, but managed by systemd (`systemctl status`,
`journalctl`, boot-time start).

`~/.config/containers/systemd/optimum-gateway.container`:

Quadlet volume paths are rooted at `%h` (your home directory), not the
current directory the earlier `podman run` example used — set up matching
directories first:

```sh
mkdir -p ~/optimum-gateway/config ~/optimum-gateway/data/libp2p ~/optimum-gateway/data/mump2p

Podman Quadlet ContainerName existing container name conflict generated systemd service documentation

💡 Result:

When using Podman Quadlet, naming conflicts for containers and systemd services are primarily managed through default naming conventions and the configuration options available in the.container file [1][2][3]. Default Naming and Conflict Avoidance By default, Quadlet generates a systemd service unit with the same name as the.container file [1][3]. To avoid conflicts with user-managed containers, the underlying Podman container created by the service is automatically named with a systemd- prefix (e.g., a file named myapp.container creates a systemd service named myapp.service and a Podman container named systemd-myapp) [1][2][4]. Configuration Options for Overriding If you need to specify a custom name or if you encounter naming collisions, you can use the following options within the [Container] section of your Quadlet file: 1. ContainerName=: This option allows you to manually specify the name of the Podman container [1][5]. If omitted, the default systemd-%N naming scheme is used [1][3]. 2. ServiceName=: This option allows you to override the default systemd service name (which is based on the filename of the.container file) [5][6][7]. Important Considerations and Behaviors Systemd and Quadlet operate within a flat namespace for unit files [8]. If you define a Quadlet file with the same name as an existing systemd service (whether it is a vendor-provided service or another custom unit), the generated Quadlet service will replace or conflict with the existing one [1][2][8]. Recent updates have improved handling for duplicate Quadlet definitions; for instance, the podman quadlet install command now includes checks to detect duplicate quadlet files in different subdirectories and can prevent accidental overwrites or duplicates [9]. However, general best practice is to ensure that your Quadlet file names are unique and descriptive to avoid unintentional overrides of systemd units [8]. If you intend to use a name already in use by another service, you must explicitly manage those conflicts, as Quadlet does not perform automated namespace isolation for service names [8].

Citations:

Preserve existing data when converting to Quadlet.

If users convert an existing bare podman run deployment, these commands create new home-rooted data directories but copy only the configuration. The explicit ContainerName=optimum-gateway can conflict with the existing container, or the new mounts can create a new peer ID and invalidate the saved CL multiaddr.

Stop the existing container and migrate both data directories before enabling Quadlet. If this section supports only fresh deployments, state that explicitly.

No in-container `HealthCmd` here — the published `getoptimum/gateway`
images don't include `curl` (or any shell utilities beyond the binary
itself), so a `HealthCmd` that shells out to `curl` never runs. Check
health from the host instead:

```sh
curl -s http://localhost:48123/health | jq
```

or point a systemd timer / your own monitoring at that same URL from
outside the container.

The API key is passed as a **Podman secret**, not a plaintext env line in
the unit file — mirrors the Kubernetes guide's use of a
[Secret](05_kubernetes.md#install) rather than a value in `values.yaml`:

POSIX sh read utility -s option stty echo standard

💡 Result:

The POSIX standard read utility does not provide an option to disable input echoing [1][2][3]. The read utility, as defined by POSIX, only supports the -r option (which prevents backslashes from being treated as escape characters) [1][3]. To suppress character echoing in a portable shell script (where read -s is not available), you must manually modify the terminal's settings using the stty utility [4][5]. The standard idiom for this is to use stty -echo before the read command and stty echo immediately afterward to restore normal terminal behavior [6][5]: stty -echo read variable_name stty echo It is strongly recommended to use a trap to ensure that terminal echoing is re-enabled if the script is interrupted (e.g., by a SIGINT) while echoing is disabled [6][7]: trap 'stty echo' 0 1 2 3 15 stty -echo read variable_name stty echo Note that stty modifies the terminal settings of standard input [4]. If standard input is redirected from a file or another process rather than being a terminal device, stty will fail or have no effect [4].

POSIX shell signal trap interrupted read command execution stty terminal echo restoration

💡 Result:

When a POSIX shell command like read is interrupted by a signal, it may leave the terminal in an inconsistent state, particularly if the command has modified terminal attributes (such as disabling echo with read -s) [1][2]. Terminal Restoration If your shell script interrupts a command that has modified terminal settings, you can restore them using the following methods: 1. stty echo: This command specifically re-enables terminal echoing [2]. 2. stty sane: This command resets the terminal to a sensible default configuration, which is generally more robust for clearing broken states [3][2]. 3. Saving and restoring state: A more reliable approach is to capture the terminal's state before modification using stty -g and restoring it later [4][5]. Recommended Pattern To ensure the terminal is restored regardless of how the script exits (e.g., via signal or normal completion), use a trap handler [6][5]. Example: # Capture the original state old_tty_settings=$(stty -g) # Define the cleanup function cleanup { stty "$old_tty_settings" exit } # Register the trap trap cleanup INT TERM EXIT # Perform the action stty -echo read -s password stty "$old_tty_settings" # Restore after success Signal Handling Nuance Be aware that behavior varies across shells and versions: - Terminal restoration by built-ins: Modern versions of shells like Bash (4.4+) take care to restore terminal settings if the shell exits due to a signal, even if that exit occurs within a trap handler [7][8]. - Trap execution: According to POSIX, if a signal for which a trap has been set is received while the shell is waiting for a foreground utility (like read), the trap is typically executed only after the utility completes [9]. If the utility is interrupted and terminates, the trap handler then runs [1]. - Race conditions: If a manual stty command in a trap executes before the shell's own cleanup logic, the manual command might be effectively reverted by the shell if it attempts to restore the state that existed when read was called [4]. This is why using stty -g to capture and restore the state is the most reliable method [4][5].

Restore terminal settings when read -r is interrupted.

read -r can be interrupted before execution reaches stty echo, leaving the terminal with echo disabled. Save the original stty -g state and restore it with a cleanup trap on exit and on signals. Clear the trap after normal restoration.

Add a focused validation for the changed secret flow.

This block changes security-sensitive input handling. Add a focused check that runs it under POSIX sh with empty and non-empty input, stubs podman secret create, and verifies that empty input never invokes it while valid input is passed through.

As per coding guidelines: “Require focused tests for non-trivial behavior changes.”

unset OPT_API_KEY_VALUE
```

`read -s` keeps the key out of your shell history — pasting the literal
`ogw_live_...` value into a command line puts it there permanently.

Then, for a user session that should keep running after logout:

```sh
loginctl enable-linger $(whoami)
systemctl --user daemon-reload
systemctl --user enable --now optimum-gateway.service
systemctl --user status optimum-gateway.service
journalctl --user -u optimum-gateway.service -f
```

Editing the `.container` file requires `daemon-reload` before it takes
effect, same as any systemd unit change — but `daemon-reload` alone does
**not** restart an already-running service with the new definition:

```sh
systemctl --user daemon-reload
systemctl --user restart optimum-gateway.service
```

## When it doesn't work

Podman-specific symptoms below. For gateway behaviour that isn't
Podman-specific (CL peering, PeerDAS, identity, log noise), see
[Troubleshooting](04_troubleshoot.md).

| Symptom | Cause |
|---|---|
| `permission denied` on `/app/config` or `/tmp/libp2p` at startup | Missing `:Z` on the volume mount, or the host directory isn't owned by your user — see [The `:Z` suffix](#the-z-suffix) |
| `mump2p_peers: 0` after a few minutes, but `cl_peers` is fine | Container is not on `--network=host` — check `podman inspect optimum-gateway --format '{{.HostConfig.NetworkMode}}'`, expect `host` |
| `self_info` shows only a private IP in `multiaddrs` | Same as above, or the host itself has no public interface |
| `Error: address already in use` on `podman run` | Another process (or a previous gateway container) already holds `33212`/`33213`/`48123` on the host — with `--network=host` there is no port remapping to fall back on |
| Peer ID changes every restart | `data/libp2p` / `data/mump2p` not persisted, or pointed at the wrong host path — confirm the bind mount source matches across restarts |
| Quadlet service won't start; `systemctl --user status` shows nothing | Run `systemctl --user daemon-reload` after creating/editing the `.container` file |
| Quadlet service stops when you log out | `loginctl enable-linger $(whoami)` was not run |
