Resolved I can not create Varnish docker instance in Plek / iptables error

[Émerson Felinto]

I went to my Plesk in the docker section and started the image "million12 / varnish".
Before running the image I have the option to set which ports this Docker instance will have access to.

However when trying to run I get the following error.
{"message":"driver failed programming external connectivity on endpoint varnish (dd04c8b5a888a82c55798134e873e7148d2b933809a74c37a42e4d22da50a6ba): (iptables failed: iptables --wait -t filter -A DOCKER ! -i docker0 -o docker0 -p tcp -d 172.17.0.2 --dport 80 -j ACCEPT: iptables: No chain/target/match by that name.\n (exit status 1))"}

What does it mean and how can I solve it?

it means that you can't have two process listening on the same port...
guess who's listening on port 80 already?

 

[MarkM]

I think he's mapping the Docker container Port 80 to 32780....

Assuming you have nothing bound to that public port, I'd check for updates to Docker... Could be a bug.

oops...

# sudo mv /var/lib/docker/network/files/ /tmp/dn-backup
# sudo systemctl restart docker

Thank you for your help.

I can not run any commands on my machine without knowing what it does exactly. Could you explain me ?

It basically installs a CLI version of a game called Snake which was made popular by Nokia back in the 90s.

 

[Émerson Felinto]

I know Snake's game of "snake"

But what does this have to do with anything? Snake? Snake ? Nokia? Docker?

???

Doesn't that install a copy of the ILOVEYOU worm (https://en.wikipedia.org/wiki/ILOVEYOU)?

... but wait... that was VBScript... hmmm... probably not. Maybe something nastier...

Makes a backup of network related docker config files (by moving them to a temporary directory) and then restarts the docker service.
But I guess it needs a

mkdir /tmp/dn-backup

first, no?


But enough giggles, where are the commands for this super awesome "snake" game you are talking about?!

It's working, thank you!

Is there a CLI version of snake? I’d be down if there was
