Quick start with snapcraft behind a proxy

This supplemental guide contains alternative steps for building Izuma Edge with snapcraft packaging in an environment with no direct Internet access (all access is routed through a proxy).

Prerequisites

In addition to the prerequisites for building without a proxy, you need:

• A build machine (physical or VM) running a recent Ubuntu Linux version (such as Ubuntu 20.04) and a user with sudo rights.

• Information about the proxy in the form protocol://proxy_user:proxy_password@proxy_host:proxy_port (for example http://myUser:[email protected]:8888).

  If you are setting up a test environment, we recommend you use Apache 2.4.48 or newer as a proxy.

Build Izuma Edge

1. Set up the environment to use the proxy (replace the example proxy data in the first line below with the real details):

   export proxy="http://myUser:[email protected]:8888"
   
   export http_proxy="$proxy" https_proxy="$proxy"
   sudo snap remove docker
   sudo apt update
   sudo apt install -y git docker.io coreutils
   git config --global http.proxy "$proxy"
   sudo usermod -a -G docker $(whoami)
   cat <<-EOT >/tmp/http-proxy.conf
   [Service]
   Environment="HTTP_PROXY=$proxy"
   Environment="HTTPS_PROXY=$proxy"
   EOT
   sudo mkdir -p /etc/systemd/system/docker.service.d
   sudo mv /tmp/http-proxy.conf /etc/systemd/system/docker.service.d/
   sudo systemctl daemon-reload
   sudo systemctl restart docker
   

2. Follow the steps from the snapcraft quick guide to clone the snap-pelion-edge repository and generate/copy the required credentials.

   DON'T run the quick start's last step (building commands) because the commands are different when using a proxy. Instead, use the step below.

3. Build with the snapcraft Docker image:

   docker build --no-cache -f Dockerfile --label snapcore/snapcraft --tag ${USER}/snapcraft:latest --build-arg http_proxy=$proxy --build-arg https_proxy=$proxy .
   docker run --rm -v "$PWD":/build --env "http_proxy=$proxy" --env "https_proxy=$proxy" -w /build ${USER}/snapcraft:latest bash -c "sudo http_proxy=$proxy https_proxy=$proxy apt-get update && snapcraft --debug"
