Working Dockerfile for mountebank-grpc about mountebank-grpc

[cbrz]

Hi @bobruub ,

I haven't had a lot of time to look into things (been busy with other projects)... There's been changes to grpc where some of the mock here was probably made obsolete. This is applicable to all custom protocols.

For mountebank-grpc it should go somehting like this (i did this on a win10 host, so adjust accordingly):

Directory Structure

Dockerfile

FROM debian:buster

    apt-get install -y --no-install-recommends curl; \

    rm -rf /var/lib/apt/lists/*; \

COPY . /etc/mountebank
WORKDIR /etc/mountebank

RUN set -ex; \
    # install mountebank global
    npm install -g mountebank; \
    # install mountebank-grpc local
    npm install ./mountebank-grpc;

ENTRYPOINT ["mb", "start", "--protofile", "protocols.json"]

protocols.json

{
    "grpc": {
        "createCommand": "node /etc/mountebank/mountebank-grpc/src/index.js"
    }
}

Build the image and run

docker build --tag=mb-grpc:latest
docker run -p 2525:2525 -p 4545:4545 --rm -it mb-grpc

After that I was able to use postman/curl to load the imposter from the README.md

PS C:\mydir\mountebank-grpc> docker run -p 2525:2525 --rm -it mb-grpc

info: [grpc:4545] [2021-08-21T21:14:08.925Z] server started on port '4545'

I didn't test the overall grpc functionality since i don't have the tools on this machine.

This should at least get you started. Hope it helps!
