Docker Compose Hybrid

Docker Compose Hybrid (build + image)

The following blog shows example of a hybrid docker-compose file which build an image and also runs a side container

Create file "my-docker-compose-hybrid.yml" with the following contents

################
version: '2'
networks:
  main:

services:
  my-python-simplehttpserver:
    container_name: my-python-simplehttpserver
    build: ./python-simplehttpserver
    ports:
      - "9080:8080"
    volumes:
      - .:/var/www/
    networks:
      main:
        aliases:
          - my-python-simplehttpserver
  my-mongo:
    container_name: my-mongo
    image: "mongo:3.2"
    ports:
      - "27017:27017"
    networks:
      main:
        aliases:
          - my-mongo
################

Create file "Dockerfile" under "python-simplehttpserver" directory with the following content:

########################
FROM ubuntu:latest

# Install python3
RUN apt-get update
RUN apt-get install -y python3

# Change to working directory
WORKDIR /var/www/

# Run http server on port 8080
EXPOSE 8080
CMD [ "python3", "-m", "http.server", "8080" ]
########################

Structure should look like this:

root-directory
              |->my-docker-compose-hybrid.yml
              |->python-simplehttpserver
                                  |-> Dockerfile

Pull docker images:

docker-compose -f ./my-docker-compose-hybrid.yml -p mydockerhybridproject pull

Start docker services:

docker-compose -f ./my-docker-compose-hybrid.yml -p mydockerhybridproject up --build -d

Test Python Http Server form host machine:

curl -v -X GET "http://localhost:9080/my-docker-compose-hybrid.yml"

Test Python Http Server from mongo container:

docker exec -it my-mongo /bin/bash

apt-get update && apt-get install curl -y

curl -v -X GET "http://my-python-simplehttpserver:8080/my-docker-compose-hybrid.yml"

exit

Stop docker services:

docker-compose -f ./my-docker-compose-hybrid.yml -p mydockerhybridproject down -v

Import self signed in Linux for Chrome / Chromium headless testing

Chrome / Chromium browser offers headless mode, which is quite useful to run tests via Selenium WebDriver in CI servers. However under some circumstance your test will hit a server with self signed certificate or invalid certificate or expired certificate. This may happen for developers trying to write tests against a server started on localhost with self signed certificates or testers trying to write tests against non-production servers with expired certificates (invalid certificates). Chrome / Chromium browser ignores the SSL errors when running in non-headless mode. However in CI servers, then it should be running in headless mode and currently we cannot ignore the SSL errors for tests accessing non-localhost websites. This blogs explains the steps for import a certificate into Linux's trust store, which will make the Chrome / Chromium browser to trust the self signed certificate.  Please do not apply these steps in production servers as it will make server vulnerable to ...

Images can be pulled form both Docker hub ( https://hub.docker.com ) or Amazon's public registry ( https://gallery.ecr.aws ) Amazon's registry is more permissive or friendly with pull rates for both clients and non-clients of AWS. This article show the setup and basics of running containers on mac. Installation command for Linux can vary based on the distribution type, hence please refer to official documentation for up-to-date steps at  https://github.com/abiosoft/colima/blob/main/docs/INSTALL.md Installation on mac: brew install docker  brew install docker-buildx brew install docker-compose brew install jq brew install colima Setup docker compose as docker plugin mkdir -p $HOME/.docker/cli-plugins ln -sfn $(which docker-compose) ...
