This image update your domains of freedns automatically every 5 minutes
For compile this image first download project, then move to project path and exec the next command
docker build -t name-image .
Replace name-image for your preferred image name
This image need only one file, this file also contains the tokens of your pages.
You can obtain your token here:
For Example:
https://freedns.afraid.org/dynamic/update.php?blablabla1232blabu
blablabla1232blabu is my token, now we'll make a file like this:
# Token my first page
blablabla1232blabu
#Token my secont page
blebleble62133blublu
In this file the text followed by # is interpreted like a comment and is not evaluated. The tokens must be written in separated lines. This file must be named freedns_tokens. In other case it will not work.
For run this image you have two options, mount file with tokens and the output of the logins will be written in the docker image or mount a folder with the file with tokens. This method allows you to view logs in the folder of your local machine.
The folder that contains the logs in the docker is /var/tmp/freedns, and the file with logs is /var/tmp/freedns_pages.log
Mount only the file with tokens
docker run --name dns-updater -v your-path/freedns_tokens:/var/tmp/freedns/freedns_tokens -d name-image
path/freedns_tokens is the file with tokens dns-updater is the name of the container name-image is the name asigned in the past
For the see logs with this method we must be enter in the container. First find the id of the image with command docker ps and later exec docker exec -it id /bin/sh this command open a terminal, in this terminal write cat /var/tmp/freedns_pages.log
Mount folder with the file with tokens
docker run --name dns-updater -v your-path:/var/tmp/freedns -d name-image
path is the path of folder dns-updater is the name of the container name-image is the name asigned in the past
For the previous logs seen with this method you only need to go to your machine folder.
If you prefer, you can use my image stated above in the docker hub. oscarsotosanchez/freedns-updater.
The execution is like stated above, but the image uses changed methods. Now we are going to view examples.
Mount only the file with tokens
docker run --name dns-updater -v your-path/freedns_tokens:/var/tmp/freedns/freedns_tokens -d oscarsotosanchez/freedns-updater
Mount folder with the file with tokens
docker run --name dns-updater -v your-path:/var/tmp/freedns -d oscarsotosanchez/freedns-updater
