--base-url argument does not work in Docker

Support
1

I have the following Dockerfile and compose.yaml to build and serve my Zola website:

# Stage 1: Build the site with Zola
FROM ghcr.io/getzola/zola:v0.20.0 AS build
ARG BASE_URL="https://wha.sh"
COPY . /project
WORKDIR /project
RUN ["zola", "build", "--base-url", "$BASE_URL"]

# Stage 2: Serve the site with Static Web Server
FROM ghcr.io/static-web-server/static-web-server:2 AS server
WORKDIR /
COPY --from=build /project/public /public

name: wha.sh
services:
  zola:
    build:
      context: .
      target: server
      args:
        BASE_URL: "http://localhost:8000"
    develop:
      watch:
        - path: .
          action: rebuild
    ports:
      - "8000:80"

When I build with docker compose build --no-cache I see in the log statements: => [zola build 4/4] RUN ["zola", "build", "--base-url", "http://localhost:8000"] 0.1s.

This shows that the ARG was read from compose.yaml and used when executing zola build.

However when I go to http://localhost:8000 and inspect anything that uses get_url I see that the base url is the name of the ARG, $BASE_URL.

I’ve tried every combination of ARG and ENV in both theDockerfile and compose.yaml and am unable to have the --base-url parameter work. I am starting to think it has to be an issue witht the Zola image rather than Docker.

i tried zola --base-url http://localhost:8000 build

and just got error: unexpected argument '--base-url' found

however im on zola 0.17.2 and that paricular arg might be valid in other versions.

you can hardcode (or even pipe) that base-url into config.toml

its possible to use a difference config file using zola --config config-prod.toml which could contain that static web server as base-url.
