Deploy Elixir Phoenix
to Alibaba Cloud VMs.

# Create the virtual server using the CLI
vxcli vm create \
  --name web-instance \
  --cloud alibaba --region ap-southeast-1 --instance-type ecs.t5-lc1m2.large \
  --key-pair-name PRODKEY1

# Save public IP address for deployment
export HOST_IP=<public-ip-from-output>

# Ensure you have a valid mix.exs in your root directory.
# Below is the typical Dockerfile compiled by our template runner:

FROM elixir:1.15-alpine AS builder
WORKDIR /app
RUN mix local.hex --force && mix local.rebar --force
ENV MIX_ENV=prod
COPY mix.exs mix.lock ./
RUN mix deps.get --only prod && mix deps.compile
COPY . .
RUN mix assets.deploy && mix release

FROM alpine:latest
WORKDIR /app
COPY --from=builder /app/_build/prod/rel/myapp ./
EXPOSE 4000
CMD ["bin/myapp", "start"]

# Trigger the container build and establish reverse proxy routes
vxcli deploy phoenix \
  --source-dir ./ \
  --app-name web-app \
  --http-port 80 \
  --app-port 4000 \
  --env PORT=4000 \
  --env DATABASE_URL=postgres://... \
  --enable-ssl \
  --domain app.example.com \
  --ssl-email [email protected] \
  --host $HOST_IP --ssh-user ubuntu --key-pair-name PRODKEY1

# app.example.com is now live with automated Let's Encrypt SSL.
