Docker config step missing? 400 reason: connect ECONNREFUSED

See original GitHub issue

I was running the docker version of this twin explorer, and getting a 400 error from the Identity.

per the docs I did:

  • Access tokens enabled
  • URI callback http://localhost:3000 added

Application runs fine, however the credential issue below.

AuthenticationError: ManagedIdentityCredential authentication failed.(status code 400).
More details:
request to failed, reason: connect ECONNREFUSED
    at ManagedIdentityCredential.<anonymous> (/usr/src/app/client/node_modules/@azure/identity/dist/index.js:1077:23)
    at Generator.throw (<anonymous>)
    at rejected (/usr/src/app/client/node_modules/@azure/identity/node_modules/tslib/tslib.js:112:69)
    at processTicksAndRejections (node:internal/process/task_queues:93:5)
  • is it required to add to the callback URI in the app, in addition to localhost?
  • is there another place in the system setup where you need to add the DT credentials?

Well, the following Dockerfile does appear to be working fine again. I’ll try to brush it up a little bit (I’ll also try to convert it into a multi-stage build in order to reduce the image size) and create a PR.

FROM node:latest

# Create app directory
WORKDIR /usr/src/app/client

# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY ./client/package*.json ./
WORKDIR /usr/src/app/client/src
RUN npm install
# If you are building your code for production
# RUN npm ci --only=production

# Bundle app source
WORKDIR /usr/src/app
COPY . .

# Install the Azure CLI, which will be required for authentication
RUN curl -sL | bash

# Notify that we want to expose port 3000
# Create startup script & start the app
WORKDIR /usr/src/app/client/src
RUN printf "#!/bin/sh\nset -e\naz login && npm run start" >
RUN chmod 0755

I can replicate the issue and would say that the problem with the authentication is related to the changes mentioned here:

I have manually tried to install the azure CLI and run az login within the docker image and that seems to work, will have to integrate that into the Dockerfile & update the instructions.
