Having some issues with my container locally resolving network requests - every so often they just h
Having some issues with my container locally resolving network requests - every so often they just hang. Works fine in prod. 
start and wait for the port to be up:start on the constructor? Is there an example?
switchPort, rather than downgrading or using containerFetch(). However, it does seem like a design inconsistency that the port must always be specified in local environments but not in production.fetch() method using a helper from @cloudflare/containers, like this:
EXPOSE working for multiple ports?

this.env.HYPERDRIVE.connectionString from my worker to container. But my Python code inside the container is not able to reach the host. Works fine if I use my origin database connection string inside Python. Also worker can connect to db with hyperdrive connection string. Only container can't. Any ideas?# syntax=docker/dockerfile:1
FROM rancher/k3s:latest
# Expose the required ports for K3s
EXPOSE 6443
EXPOSE 443
EXPOSE 80
# Set the default command to run K3s server
CMD ["server", "--disable", "traefik"]export class MyContainer extends Container {
defaultPort = 6443;
requiredPorts = [6443, 443, 80];
// ...
}
app.get("/readyz", async (c) => {
const container = getContainer(c.env.MY_CONTAINER);
return await container.fetch(c.req.raw);
});
