Fails to install on ubuntu (via docker/node)

[luisrayas3]

I tried installing on my local ubuntu machine and when that didn't work (thought it was my version of node/npm) I tried installing in a docker container:

$ docker pull node:16
$ cat c4builder.Dockerfile
FROM node:16
RUN npm i -g c4builder
$ docker build -t c4builder - < c4builder.Dockerfile

This fails:

I get the same error using node:alpine or node:17 as the FROM

node:16 image doesn't have Java environment. Instead, you can use timbru31/java-node:latest image as a solution.

I recently wrote a Dockerfile that can be used to containerize the c4builder tool using a Linux base image.

This has now been merged into the main branch of the c4-builder repo, see: https://github.com/adrianvlupu/C4-Builder/blob/master/Dockerfile

@craigwardman could you publish official image on docker hub?

[craigwardman]

it's not an official image, but I have built the Dockerfile (using 0.2.16 version of c4builder) and pushed it to docker hub under my account, so if you want to run it directly you can use:

docker run -v $(pwd):/pwd craigwardman/c4builder
