Error: /bin/sh: java: not found with @openapitools

I'm trying to run an Angular app container with this docker file:

# stage 1
FROM node:alpine AS my-app-build
WORKDIR /app
COPY . .
RUN npm install @openapitools/openapi-generator-cli -g
RUN npm run build

# stage 2
FROM nginx:alpine
COPY --from=my-app-build /app/dist/ /usr/share/nginx/html
EXPOSE 80

I need openapitools to generate my client api but I get this error message:

/usr/local/lib/node_modules/@openapitools/openapi-generator-cli/main.js:636
                error ? reject(new Error(stderr)) : resolve(stdout);
                               ^

Why do I need java? Do I have to install it?

Solution

  • Yes you need to install java, or use another openapi generator.

    For a angular project I use ng-openapi-gen. This does not need it, and there are probably others.
