reproducible docker image failing

[techsmyth]

Docker images are failing when embedding the sdk.

To re-produce:

• cd service_agent
• docker build .

The above error will be generated.

Hi @techsmyth

There's a working Dockerfile already available at sdk/Dockerfile:

FROM node:14
MAINTAINER Jolocom Dev <dev@jolocom.io>

WORKDIR /app
VOLUME /app

COPY docker-entrypoint.sh /usr/local/bin/

CMD ["start"]

The main difference is that it is FROM node:14 which uses ubuntu (not alpine). If you want to use alpine you need the libc6-compat package I believe

The SDK Dockerfile is referenced in the service_agent section in the docker-compose.yml by specifying build:

services:
  service_agent:
    build: ./sdk
    image: jolocom/sdk
    restart: unless-stopped

@mnzaki thanks for the follow up.

Basically it comes down to how to run the jolocom-sdk on an alpine based image. Using the node:12 image as base worked fine, but the image size for out server image went from 700mb to 1500mb :(

adding apk add libc6-compat to the dockerfile did not help. No more bandwidth near term for me to look at this - and too risky (as well as too big an image size jump) to move to node:12 instead of node:12-alpine.

So for now leaving jolocom-sdk disabled in our server image, can still demo locally as needed. If anything comes up re running jolocom-sdk on a node:12-alpine base (or node:14-alpine) please let me know.
