Hey iam using docker with 6 rails microservices.
Everytime i start the containers i get huge output of logs, is there a way to minify that?
Just want to give out something like " 6 of 6 containers startet succesfully" as example.
If you want to silent some of the services, you can use something like this. It will disable the logs.
https://docs.docker.com/config/containers/logging/configure#supported-logging-drivers
```
redis:
image: redis:latest
logging:
driver: none
```
I am successfully running the code for this episode. Except the test database will not create due to this error: PG::ConnectionBad: could not translate host name "postgres://postgres:postgres@postgres:5432" to address: Name or service not known
☒ Is the postgres instance running? You can run docker container ls to see. You can also run docker logs CONTAINER_NAME to see if there is something else weird going on.
If anyone is wanting to use an Alpine version of a Ruby image, here's what I'm using. I've included some commented out lines which you can replace the postgresql-dev with the sqlite or mysql (mariadb) depending on the database you're using.
FROM ruby:2.6.6-alpine3.12
LABEL MAINTAINER=dave@k-innovations.net
# sqlite-dev \# mariadb-dev \
RUN apk add --no-cache --update build-base \
git \
postgresql-dev \
nodejs \
yarn \
tzdata \
&& rm -rf /var/cache/apk/*
RUN bundle config --global frozen 1
COPY Gemfile Gemfile.lock ./
RUN gem update --system
RUN gem install bundler
RUN bundle install -j $(nproc)
RUN mkdir -p /app
WORKDIR /app
This helped reduce the base image from 2GB to 1GB.

Advice?
