Traefik v2: docker-compose repo

Traefik v2

How to use this repo:

Clone the repo using:

$ git clone https://github.com/sseifert/docker-compose.git $HOME/docker/traefik2

Then create the environment variable, $TRAEFIK2DIR which points to this directory. I've been using a .bash_aliases file to identify my environment variables with:

$ vim $HOME/.bash_aliases

export TRAEFIK2DIR="$HOME/docker/traefik2"

Reload your .bash_aliases file using:

$ source $HOME/.bash_aliases

I've been using this method in order to maintain the same configuration across different hosts by copying/syncing my .bash_aliases file.

Starting/Stopping Containers

You can include the following in your .bash_aliases file in order to bring up Docker containers, e.g. dup traefik:

dup() {
  docker-compose -f $TRAEFIK2DIR/ymlfiles/$1.yml -p $1 up -d
}

and to bring down containers, e.g. ddown traefik:

ddown() {
  docker-compose -f $TRAEFIK2DIR/ymlfiles/$1.yml -p $1 down
}

Other environment variables you will need:

• CLOUDFLARE_EMAIL
• CLOUDFLARE_API_KEY
• DOMAINNAME
• MY_EMAIL
• GOOGLE_CLIENT_ID
• GOOGLE_CLIENT_SECRET
• OAUTH_SECRET
• ... and a few others

Traefik_proxy Network

Create the traefik_proxy network with:

$ docker network create traefik_proxy

or specify the subnet that you want to use (as long as it's in the private IP space). My server is at 192.168.1.50, so I figure a 192.168.50.0/24 subnet will be easy to identify with that server's docker network. I use this method so that I can assign static IPs to containers.

$ docker network create --gateway 192.168.50.1 --subnet 192.168.50.0/24 traefik_proxy

or create a macvlan network with:

$ docker network create -d macvlan --subnet=192.168.1.0/24 --ip-range=192.168.1.128/25 --gateway=192.168.1.1 -o parent=eth0 traefik_proxy

If you create a macvlan network make sure your DHCP server doesn't assign addresses above .127 .

Note: your services on the macvlan network won't be available by the host. This means, for example, that the host couldn't use a pihole on the macvlan network, although all other services and devices could access the pihole. This may not be an issue if you only access the services on other devices, and you run pihole on a dedicated raspberry pi ;-). There's a way around this by modifying your host network config, but I haven't figured that part out yet.

I'm currently using the second method, which is a bridge network with a defined gateway and subnet.

How I actually bring up/down my containers

I use a scripts folder $HOME/.scripts where I have the following file "dup":

#!/bin/sh
# $HOME/.scripts/dup

echo $(basename "$0")
CONTAINERS="$@"
for c in $CONTAINERS
do
  echo ""
  echo "...$c up..."
  echo ""
  docker-compose -f "$TRAEFIK2DIR/ymlfiles/$c.yml" -p $c up -d
  done"

Then, in my .bash_aliases file I've added:

export PATH="$PATH:$HOME/.scripts"

Now it's possible to bring up multiple projects at the same time with dup traefik bitwarden plex etc. The script will go in a loop and start each service in order.

A similar ddown script can be created to bring multiple services down:

#!/bin/sh
# $HOME/.scripts/ddown

CONTAINERS="$@"
for c in $CONTAINERS
do
  echo ""
  echo "...$c down..."
  echo ""
  docker-compose -f "$TRAEFIK2DIR/ymlfiles/$c.yml" -p $c down
  done

Now I have a line saved in my notes of all my "standard" services so that I can start/stop them easily. I have two lines saved: One starts the database containers first, the other lists the databases at the end so that they're stopped last.
