Proxy errors when running pulumi automation script in a docker container behind a corporate proxy

[simonjcarr]

Hi,
I have created a javascript pulumi automation API script. The script uses local storage for state. The script runs fine on a VM behind a corporate proxy. but when I try to dockerize the script and run the docker container on the server with the same proxy server I get errors suggesting that pulumi is not able to connect to the internet.

Here are the errors I am getting

"https:" scheme not supported in proxy URI

pulumi:pulumi:Stack pulumidevelopment-dev creating (60s) warning: error downloading provider: Get "https://get.pulumi.com/releases/plugins/pulumi-resource-vsphere-v4.10.0-linux-amd64.tar.gz": proxyconnect tcp: dial tcp 10.113.3.3:3129: i/o timeout

Here is my Dockerfile

FROM node:18

RUN npm config set proxy http://10.114.3.3:3128
RUN npm config set strict-ssl false

ENV http_proxy http://10.114.3.3:3128
ENV https_proxy http://10.114.3.3:3128
ENV no_proxy 10.114.3.3,10.114.12.5,localhost,127.0.0.1

ENV PULUMI_ACCESS_TOKEN redacted
ENV PULUMI_CONFIG_PASSPHRASE redacted
ENV VSPHERE_USER "redacted"
ENV VSPHERE_PASSWORD "redacted"

#Add certificate
COPY ca.crt /usr/local/share/ca-certificates/ca.crt

RUN chmod 644 /usr/local/share/ca-certificates/ca.crt && update-ca-certificates

# Prepare the working directory
WORKDIR /app
COPY package.json /app/
RUN npm install
COPY . /app/

RUN pulumi login --local

# Command to run your application
CMD ["node", "index.js"]

A string thing is that the error message above refers to not being able to connect to 10.113.3.3:3129 but as you can see in my Dockerfile the IP Address of my proxy is 10.114.3.3:3128

I can't understand why this works on the same VM but fails in the docker container.
