I am new in Docker and I have installed apache from the image httpd:2.4 and name tecmint-web. I am trying to configure apache but I have no idea how to do it. I tried the following steps:

docker exec -it tecmint-web /bin/bash

ls

cd conf

ls

And the ouput of the ls is : extra httpd.conf magic mime.types original When I try to open httpd.conf with an editor, an error appears : command not found

I am doing anything wrong? How is it possible to configure apache?

  • In general, you do not start a container and start interactively changing config files. You create the config before hand and mount it into the container.

According to the documentation of the official Docker image, to configure the Apache HTTP server, you can:

  1. Copy the configuration file from the image to your host with:
docker run --rm httpd:2.4 cat /usr/local/apache2/conf/httpd.conf > my-httpd.conf

  1. Edit locally the my-httpd.conf

  2. Build a new image, with the modified configuration file:

The Dockerfile:

FROM httpd:2.4
COPY ./my-httpd.conf /usr/local/apache2/conf/httpd.conf

Build the image with:

docker build -t my-configured-http-server .

You can also use Docker Compose with the original image and a mapped configuration file:

The docker-compose.yml file:

version: '3'

services:
  my-http-server:
    image: httpd:2.4
    volumes:
      - ${PWD}/my-httpd.conf:/usr/local/apache2/conf/httpd.conf
