Alpine and apk add fails (hangs, killed)

General

Hi,
I’m trying to build a simple image with Alpine and some packages which exits in a strange way.
Purpose is to package a vue web application into a container.
Trying to build this Dockerfile:

FROM alpine:latest
RUN apk update && apk upgrade &&
apk add --no-cache bash git openssh
RUN apk add --update python krb5 krb5-libs gcc make g++ krb5-dev
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY . /usr/src/app/
RUN npm install
RUN npm install pm2 -g
WORKDIR /usr/src/app
EXPOSE 8080
CMD [ “pm2-runtime”,“start”,“ecosystem.config.js”,“–only”,“dev” ]

Results in:

Sending build context to Docker daemon 131.2MB

Also tried to manually do it results in the following (sometimes it hangs, sometimes it says “killed” after 1%:

$ docker run -it --rm alpine:3.7 /bin/sh

Solved by upgrading my Ubuntu Bionic 18.04 to Disco 19.04. Something must have been really messed up but have no idea what.
