Unable to resolve resource

[Weissnix4711]

Getting this error when trying to open container.

Unable to resolve resource <remote url>

Output of Remote OSS extension is just connecting to local... nothing else.

And the output of reh in the container..

Server bound to 127.0.0.1:8000 (IPv4)
Extension host agent listening on 8000

[12:58:42] Extension host agent started.

settings.json:

{
  ...
  "remote.OSS.hosts": [
    {
      "type": "manual",
      "name": "local",
      "host": "172.17.0.2",
      "port": 8000,
      "folders": [
        {
          "name": "hass-core",
          "path": "/workspaces/hass-core"
        }
      ]
    }
  ]
}

Running this in the container before connecting:

export VSCODIUM_DIR=~/.vscodium-server
export VSCODIUM_VERSION="1.71.0.22245"
export PACKAGE="vscodium-reh-linux-x64-${VSCODIUM_VERSION}.tar.gz"

mkdir -p "${VSCODIUM_DIR}"
pushd "${VSCODIUM_DIR}"
wget "https://github.com/VSCodium/vscodium/releases/download/${VSCODIUM_VERSION}/${PACKAGE}"
export COMMIT=$(tar -xf "${VSCODIUM_DIR}/${PACKAGE}" ./product.json -O | jq ".commit" -r)
export BIN_DIR="${VSCODIUM_DIR}/bin/${COMMIT}"

mkdir -p "${BIN_DIR}"
pushd "${BIN_DIR}"
tar -xf "${VSCODIUM_DIR}/${PACKAGE}"
popd

ln -sf "${BIN_DIR}" "${VSCODIUM_DIR}/bin/current"
rm "${VSCODIUM_DIR}/${PACKAGE}"

popd


export CONNECTION_TOKEN=MySecretToken
export REMOTE_PORT=8000

~/.vscodium-server/bin/current/bin/codium-server \
    --host localhost \
    --port ${REMOTE_PORT} \
    --telemetry-level off \
    --connection-token ${CONNECTION_TOKEN}

The container was made with the original devcontainers extension. I then disabled that extension, enabled Remote OSS, restarted the container (which was stopped, but not removed), attached to a shell and ran the above commands to install and start vscodium-server.

Here is the original devcontainer.json from which the container was created:

From https://github.com/home-assistant/core if it's of any help.

As far as I am aware, this should work just fine. But evidently I'm missing something.

I have a hard time reproducing this as I do not use devcontainers myself. Can you access the vscodium-server on the local port by the following?

curl -v localhost:8000/version

This should reply with the commit of the server.

The %2B in the URL looks suspect here, it should be + unescaped, I believe. I have a lot more luck using this form of URL: vscodium://vscode-remote/remote-oss+${REMOTE_NAME}${REMOTE_PATH}. So for this issue: vscodium://vscode-remote/remote-oss+local/workspaces/hass-core

I ran into the same problem. In addition to the same error message, I received an error saying that the connection was "reset by peer" when trying to connect to localhost:8000/version (and other variants like 0.0.0.0, [::], etc.), both via curl and my web browser.

I resolved the issue by setting the REH's host in my container to use 0.0.0.0 instead of localhost.

In other words, this seems to be a rootless Podman/Docker limitation I reckon.

Edit: I also have a repo documenting some of my experimentation with using the extension with podman so people can hopefully get started faster than I did.
