Examples

Any of the commands can be run at creation with docker run or later with docker exec -it smokeping.sh (as of version 1.3 of docker).

Setting the Timezone

sudo docker run -it -p 8000:80 -d dperson/smokeping -T EST5EDT

OR using environment variables

sudo docker run -it -p 8000:80 -e TZ=EST5EDT -d dperson/smokeping

Will get you the same settings as

sudo docker run -it --name smokeping -p 8000:80 -d dperson/smokeping
sudo docker exec -it smokeping smokeping.sh -T EST5EDT \
            ls -AlF /etc/localtime
sudo docker restart smokeping

Start smokeping, clear targets, setup a new one to the first hop from ISP:

IP=$(traceroute -n google.com |
            egrep -v ' (10|172\.(1[6-9]|2[0-9]|3[01])|192.168)\.' |
            awk '/[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+.*ms/ {print $2; exit}')
sudo docker run -it -p 8000:80 -d dperson/smokeping -w -t "ISP;NextHop;$IP"

OR

IP=$(traceroute -n google.com |
            egrep -v ' (10|172\.(1[6-9]|2[0-9]|3[01])|192.168)\.' |
            awk '/[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+.*ms/ {print $2; exit}')
sudo docker run -it -p 8000:80 -e WIPE=y -e TARGET="ISP;NextHop;$IP" \
            -d dperson/smokeping

To add additional targets (replace values in <> with your own):

sudo docker exec -it <name_of_instance> smokeping.sh -t "<site;name;target>"

IE

sudo docker exec -it stunned_newton smokeping.sh \
            -t "home;router;bob.dyndns.org"

Start smokeping, and configure sSMTP to forward alerts:

sudo docker run -it -p 8000:80 -d dperson/smokeping \
            -g "sampleuser;samplepass"

OR

sudo docker run -it -p 8000:80 -e SSMTP_GMAIL="sampleuser;samplepass" \
            -d dperson/smokeping

Start smokeping, and configure owners email address:

sudo docker run -it -p 8000:80 -d dperson/smokeping \
            -e "sampleuser@gmail.com"

OR

sudo docker run -it -p 8000:80 -e EMAIL="sampleuser@gmail.com" \
            -d dperson/smokeping

Start smokeping, and configure owners name:

sudo docker run -it -p 8000:80 -d dperson/smokeping -o "Sample User"

OR

sudo docker run -it -p 8000:80 -e OWNER="Sample User" -d dperson/smokeping

Complex configuration

Example configs

If you wish to adapt the default configuration, use something like the following to copy it from a running container:

sudo docker cp smokeping:/etc/smokeping /some/path

You can use the modified configuration with:

sudo docker run -it --name smokeping -p 8000:80 \
            -v /some/path:/etc/smokeping:ro -d dperson/smokeping
