wip has moved

Future work on this repository has moved to the monorepo valera-rozuvan/docker-recipes. This repo is archived for historic purposes (to preserve commit history). Navigate over to docker-recipes/docker-apache2-file-server to see updates (if any).

introduction

Run an Apache2 static file server via Docker. Key features:

• specify port at runtime
• map random virtual path to host folder

Build

sudo docker build -t file-server .

Run

Decide on the port number you want apache2 to run on. For this example, port 7154 was chosen. Please modify below commands accordingly, if you choose a different port number.

sudo docker run \
  --name file-server-7154 \
  -v /absolute/host/path/to/data/folder:/var/www/html/RANDOM_STRING_FT67VGF667GH \
  -e APACHE_LISTEN_PORT='7154' \
  -p 7154:7154 \
  --expose 7154 \
  --memory="400m" \
  --memory-swap="1g" \
  -d \
  file-server

You can now go to http://localhost:7154/RANDOM_STRING_FT67VGF667GH and see your files. If you can open port 7154 on your host system to the world, and your host has an external IP, you will be able to also access files via your IP.

Check container stats

sudo docker ps -q | xargs sudo docker stats --no-stream

Check container volume mounts

$ sudo docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
754a56c8facc        file-server         "/usr/sbin/apache2 -…"   22 hours ago        Up 22 hours         0.0.0.0:7154->7154/tcp   file-server-7154

$ sudo docker inspect -f "{{ .Mounts }}" 754a56c8facc
[{bind  /absolute/host/path/to/data/folder /var/www/html/RANDOM_STRING_FT67VGF667GH   true rprivate}]

Stop container

sudo docker stop file-server-7154
sudo docker rm file-server-7154

cgroup config

If you get some warning about --memory-swap flag, then you need to update /etc/default/grub and set:

GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"

For this to propagate to the kernel, run update-grub && reboot.

Enjoy ;)
