Docker Install Apache

Method#1: docker pull httpd

Find the httpd image on Docker Hub:

Docker Install Apache

You can check other versions of httpd by Sort by, the default is the latest version httpd:latest.

In addition, we can also use the docker search httpd command to see the available versions.

apidemos@apidemos:~/apache$ docker search httpd

Here we pull the official mirror:

apidemos@apidemos:~/apache$ docker pull httpd

After waiting for the download to complete, we can check the local mirror list for the image with REPOSITORY as httpd.

apidemos@apidemos:~/apache$ docker images httpd
REPOSITORY     TAG        IMAGE ID        CREATED           SIZE

Method#2: Build via Dockerfile

Create Dockerfile

First, create the directory apache, which will be used to store related stuff later.

apidemos@apidemos:~$ mkdir -p ~/apache/www ~/apache/logs ~/apache/conf

The www directory will be mapped to the apache container configuration application directory.

The logs directory will be mapped to the apache container’s log directory.

The configuration files in the conf directory will be mapped to the configuration files of the apache container.

Go to the created apache directory and create the Dockerfile.

COPY httpd-foreground /usr/local/bin/

EXPOSE 80
CMD ["httpd-foreground"]

COPY httpd-foreground /usr/local/bin/ in the Dockerfile file is to copy httpd-foreground from the current directory into the image as the httpd service startup script, so we have to create a script file httpd-foreground locally.

#!/bin/bash
set -e

# Apache gets grumpy about PID files pre-existing
rm -f /usr/local/apache2/logs/httpd.pid

exec httpd -DFOREGROUND

Grant executable permissions to the httpd-foreground file.

apidemos@apidemos:~/apache$ chmod +x httpd-foreground

Create an image via Dockerfile and replace it with your own name.

apidemos@apidemos:~/apache$ docker build -t httpd .

Once created, we can find the image we just created in the local list of mirrors.

apidemos@apidemos:~/apache$ docker images httpd
REPOSITORY     TAG        IMAGE ID        CREATED           SIZE
httpd          latest     da1536b4ef14    23 seconds ago    195.1 MB

Use apache image

Run the container

docker run -p 80:80 -v  $PWD/www/:/usr/local/apache2/htdocs/ -v$ PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf -v $PWD/logs/:/usr/local/apache2/logs/ -d httpd

Command Description.

-p 80:80: The first port 80 is the host port, the next one is the container port, the effect is to map the container’s port 80 to the host’s port 80.

-v $PWD/www/:/usr/local/apache2/htdocs/: Mount the www directory in the current directory of the host to /usr/local/apache2/htdocs/ of the container.

-v $PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf: Mount the conf/httpd.conf file from the current directory in the host to the container’s /usr/local/apache2/conf/httpd.conf.

-v $PWD/logs/:/usr/local/apache2/logs/: Mount the logs directory in the current directory of the host to /usr/local/apache2/logs/ of the container.

For more detailed commands, please refer to: Docker run command

To view the container startup status.
