🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not generate Docker commands when no runtime is selected.

Line 100 defaults to Docker when detection returns null. src/components/LocalComputerSection.tsx renders commands.pull and commands.run, so users without a runtime see Docker commands although the setup guidance recommends Colima or Podman. Keep runtime-specific commands unavailable until detection selects a runtime, and hide dependent setup commands until then.

In `@server/container-computer.ts` around lines 99 - 104, Update setupCommands to
return no runtime-specific commands when runtime is null instead of defaulting
to Docker, and adjust the dependent setup-command rendering in
LocalComputerSection so pull and run guidance remains hidden until a runtime is
detected. Preserve the existing command generation for selected runtimes.

Docker Podman Apple container CLI publish port host IP 127.0.0.1 syntax

💡 Result:

To publish a container port to the local loopback interface (127.0.0.1) on the host, both Docker and Podman use the same syntax for the publish flag [1][2][3]. By including the IP address in the port mapping, you restrict access to the containerized service so that it is only reachable from the host machine itself, rather than from the wider network [1][4][3]. The syntax is: -p 127.0.0.1:HOST_PORT:CONTAINER_PORT For example: docker run -p 127.0.0.1:8080:80 nginx podman run -p 127.0.0.1:8080:80 nginx Key details: - By default, if you only specify the ports (e.g., -p 8080:80), the container is published on all network interfaces (0.0.0.0), making it accessible to any machine that can reach your host [5][6][3]. - Specifying 127.0.0.1 explicitly forces the binding to the loopback interface [1][7]. - You can also bind to specific IPv6 addresses using the same format by enclosing the address in brackets, for example: -p '[::1]:8080:80' [1]. - If you omit the host port but keep the IP (e.g., -p 127.0.0.1::80), the container port will be mapped to a randomly assigned ephemeral port on the host's loopback interface [2][8]. Always verify your port mappings after starting the container by running: docker port <container_name_or_id> podman port <container_name_or_id>

site:github.com/apple/container CLI run --publish 127.0.0.1 port

💡 Result:

The --publish (or -p) flag is used in container CLI tools (such as Apple's container utility) to forward traffic from a specific host port to a container port [1][2]. The supported format for this option is [host-ip:]host-port:container-port[/protocol] [1][3]. To publish a port specifically to the IPv4 loopback address (127.0.0.1), you use the following syntax: --publish 127.0.0.1:host-port:container-port For example, to forward traffic from port 8080 on your host's 127.0.0.1 interface to port 8000 inside the container, you would use: container run -d -p 127.0.0.1:8080:8000 <image_name> [1][4] Important Considerations: - Protocol: You can optionally specify the protocol (tcp or udp) by appending it to the end, for example: -p 127.0.0.1:8080:8000/tcp [1][2]. - IPv6 Loopback: To publish to the IPv6 loopback address (::1), you must enclose the address in brackets: -p '[::1]:8080:8000' [1][4]. - Connectivity Issues: If you encounter connection issues (e.g., connection reset or empty reply) when using 127.0.0.1, ensure that your container application is actually listening on 127.0.0.1 inside the container, or try binding to 0.0.0.0 (all interfaces) if necessary [4][5]. Additionally, on macOS, check that your container runtime has the required network permissions [6].

Apple container CLI documentation port forwarding publish host IP

💡 Result:

When using the Apple container CLI, port forwarding is configured via the --publish (or -p) option [1][2]. The syntax for binding a container port to a specific host IP address is: [host-ip:]host-port:container-port[/protocol] If you specify the host-ip, traffic will be forwarded only from that specific host interface to the container [3][2]. If the host-ip is omitted, the default behavior is typically to bind to all available host interfaces [4][5]. For example: - To bind container port 80 to port 8080 on the IPv4 loopback interface (127.0.0.1): container run -p 127.0.0.1:8080:80 [image] [3][2] - To bind container port 80 to port 8080 on the IPv6 loopback interface ([::1]): container run -p '[::1]:8080:80' [image] [3][2] The protocol (tcp or udp) can be specified by appending it to the container port (e.g.,:80/udp) [1][2]. If no protocol is specified, TCP is used by default [2]. When a container is attached to multiple networks, published ports generally forward to the IP address of the interface attached to the first network [3][2].

Line 104 exposes the VNC and noVNC ports on all host interfaces. Use -p 127.0.0.1:6080:6080 -p 127.0.0.1:5900:5900 for Docker, Podman, and container.
