What is Apache?
The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows NT. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.
TL;DR;
$ docker run --name apache bitnami/apache:latest
Docker Compose
$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-apache/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d
Why use Bitnami Images?
- Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
- With Bitnami images the latest bug fixes and features are available as soon as possible.
- Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
- Bitnami images are built on CircleCI and automatically pushed to the Docker Hub.
- All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading linux distribution.

Get this image
The recommended way to get the Bitnami Apache Docker Image is to pull the prebuilt image from the Docker Hub Registry.
$ docker pull bitnami/apache:latest
To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.
$ docker pull bitnami/apache:[TAG]
If you wish, you can also build the image yourself.
$ docker build -t bitnami/apache:latest https://github.com/bitnami/bitnami-docker-apache.git
Hosting a static website
The /app
path is configured as the Apache DocumentRoot. Content mounted here is served by the default catch-all virtual host.
$ docker run --name apache -v /path/to/app:/app bitnami/apache:latest
or using Docker Compose:
version: '2'
services:
apache:
image: 'bitnami/apache:latest'
ports:
- '80:8080'
- '443:8443'
volumes:
- /path/to/app:/app
Accessing your server from the host
To access your web server from your host machine you can ask Docker to map a random port on your host to ports 8080
and 8443
exposed in the container.
$ docker run --name apache -P bitnami/apache:latest
Run docker port
to determine the random ports Docker assigned.
$ docker port apache
8443/tcp -> 0.0.0.0:32768
8080/tcp -> 0.0.0.0:32769
You can also manually specify the ports you want forwarded from your host to the container.
$ docker run -p 8080:8080 -p 8443:8443 bitnami/apache:latest
Access your web server in the browser by navigating to http://localhost:8080.
Configuration
Environment variables
When you start the Apache image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the docker run command line. If you want to add a new environment variable:
- For docker-compose add the variable name and value under the application section:
version: '2'
services:
apache:
image: 'bitnami/apache:latest'
labels:
kompose.service.type: nodeport
ports:
- '80:8081'
- '443:8443'
environment:
- APACHE_HTTP_PORT_NUMBER=8081
volumes:
- 'apache_data:/bitnami'
volumes:
apache_data:
driver: local
- For manual execution add a
-e
option with each variable and value:
$ docker run -d --name apache -p 80:8081 -p 443:443 \
--network apache-tier \
--e APACHE_HTTP_PORT_NUMBER=8081 \
--volume /path/to/apache-persistence:/bitnami \
bitnami/apache:latest
Available variables:
APACHE_HTTP_PORT_NUMBER
: Port used by Apache for HTTP. Default: 8080APACHE_HTTPS_PORT_NUMBER
: Port used by Apache for HTTPS. Default: 8443
Adding custom virtual hosts
The default httpd.conf
includes virtual hosts placed in /bitnami/apache/conf/vhosts/
. You can mount a my_vhost.conf
file containing your custom virtual hosts at this location.
For example, in order add a vhost for www.example.com
:
my_vhost.conf
file with the following content.
Step 1: Write your <VirtualHost *:8080>
ServerName www.example.com
DocumentRoot "/app"
<Directory "/app">
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
Step 2: Mount the configuration as a volume.
$ docker run --name apache \
-v /path/to/my_vhost.conf:/bitnami/apache/conf/vhosts/my_vhost.conf:ro \
bitnami/apache:latest
or using Docker Compose:
version: '2'
services:
apache:
image: 'bitnami/apache:latest'
ports:
- '80:8080'
- '443:8443'
volumes:
- /path/to/my_vhost.conf:/bitnami/apache/conf/vhosts/my_vhost.conf:ro
Using custom SSL certificates
NOTE: The steps below assume that you are using a custom domain name and that you have already configured the custom domain name to point to your server.
This container comes with SSL support already pre-configured and with a dummy certificate in place (server.crt
and server.key
files in /bitnami/apache/conf/bitnami/certs
). If you want to use your own certificate (.crt
) and certificate key (.key
) files, follow the steps below:
Step 1: Prepare your certificate files
In your local computer, create a folder called certs
and put your certificates files. Make sure you rename both files to server.crt
and server.key
respectively:
$ mkdir /path/to/apache-persistence/apache/conf/bitnami/certs -p
$ cp /path/to/certfile.crt /path/to/apache-persistence/apache/conf/bitnami/certs/server.crt
$ cp /path/to/keyfile.key /path/to/apache-persistence/apache/conf/bitnami/certs/server.key
Step 2: Run the Apache image
Run the Apache image, mounting the certificates directory from your host.
$ docker run --name apache \
-v /path/to/apache-persistence/apache/conf/bitnami/certs:/bitnami/apache/conf/bitnami/certs \
bitnami/apache:latest
or using Docker Compose:
version: '2'
services:
apache:
image: 'bitnami/apache:latest'
ports:
- '80:8080'
- '443:8443'
volumes:
- /path/to/apache-persistence/apache/conf/bitnami/certs:/bitnami/apache/conf/bitnami/certs
Full configuration
The image looks for configurations in /bitnami/apache/conf/
. You can mount a volume at /bitnami
and copy/edit the configurations in the /bitnami/apache/conf/
. The default configurations will be populated in the conf/
directory if it's empty.
Step 1: Run the Apache image
Run the Apache image, mounting a directory from your host.
$ docker run --name apache \
-v /path/to/apache-persistence:/bitnami \
bitnami/apache:latest
or using Docker Compose:
version: '2'
services:
apache:
image: 'bitnami/apache:latest'
ports:
- '80:8080'
- '443:8443'
volumes:
- /path/to/apache-persistence:/bitnami
Step 2: Edit the configuration
Edit the configuration on your host using your favorite editor.
$ vi /path/to/apache-persistence/apache/conf/httpd.conf
Step 4: Restart Apache
After changing the configuration, restart your Apache container for the changes to take effect.
$ docker restart apache
or using Docker Compose:
$ docker-compose restart apache
Reverse proxy to other containers
Apache can be used to reverse proxy to other containers using Docker's linking system. This is particularly useful if you want to serve dynamic content through an Apache frontend.
Further Reading:
Logging
The Bitnami Apache Docker image sends the container logs to the stdout
. To view the logs:
$ docker logs apache
or using Docker Compose:
$ docker-compose logs apache
You can configure the containers logging driver using the --log-driver
option if you wish to consume the container logs differently. In the default configuration docker uses the json-file
driver.
Maintenance
Upgrade this image
Bitnami provides up-to-date versions of Apache, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container.
Step 1: Get the updated image
$ docker pull bitnami/apache:latest
or if you're using Docker Compose, update the value of the image property to
bitnami/apache:latest
.
Step 2: Stop and backup the currently running container
Stop the currently running container using the command
$ docker stop apache
or using Docker Compose:
$ docker-compose stop apache
Next, take a snapshot of the persistent volume /path/to/apache-persistence
using:
$ rsync -a /path/to/apache-persistence /path/to/apache-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)
You can use this snapshot to restore the database state should the upgrade fail.
Step 3: Remove the currently running container
$ docker rm -v apache
or using Docker Compose:
$ docker-compose rm -v apache
Step 4: Run the new image
Re-create your container from the new image.
$ docker run --name apache bitnami/apache:latest
or using Docker Compose:
$ docker-compose up apache

Notable Changes
2.4.34-r8
- The Apache container has been migrated to a non-root user approach. Previously the container ran as the
root
user and the Apache daemon was started as theapache
user. From now on, both the container and the Apache daemon run as user1001
. As a consequence, the HTTP/HTTPS ports exposed by the container are now 8080/8443 instead of 80/443. You can revert this behavior by changingUSER 1001
toUSER root
in the Dockerfile.
2.4.18-r0
- The configuration volume has been moved to
/bitnami/apache
. Now you only need to mount a single volume at/bitnami/apache
for persisting configuration./app
is still used for serving content by the default virtual host. - The logs are always sent to the
stdout
and are no longer collected in the volume.
2.4.12-4-r01
- The
/app
directory is no longer exported as a volume. This caused problems when building on top of the image, since changes in the volume are not persisted between DockerfileRUN
instructions. To keep the previous behavior (so that you can mount the volume in another container), create the container with the-v /app
option.
