I have got two machines:
10.0.1.41 - rancher server and host with some docker containers inside
10.0.1.30 - rancher host without any container (only rancher-agent in)
Cloning a container from 10.0.1.41 to 10.0.1.30 it’s giving me the “Validation failed in API: PortWrongFormat” error.
How to debug, fix, solve this?

What version of Rancher are you using?
Are you cloning a service or container?
Also, what do you mean by “cloning a container from host A to Host B”? How are you doing that?

Hi Denise,

I am unable to reproduce.
How are you cloning from Host A to Host B? How do you know that your are making that change?

Yes, we have been a bit busy with getting v0.56.0 and v0.56.1 out.
I was finally able to reproduce and have filed this Github issue. Is there a reason why you are using standalone containers versus services? Using services (even scale of 1) allows you to leverage a lot more of the Rancher features.

Hi Denise,
thanks for your answer, i’m really glad to receive that.
Anyway i need to understand better; how can i use services?
I create my images from a dockerfile (building) and i use that with a docker-compose.yml.
Can you give me some indications?
Thank you really much.

In order to launch a docker-compose file into Rancher, you’ll need to use rancher-compose. There are many links within the rancher-compose section of the docs page.
[http://docs.rancher.com/rancher/rancher-compose/](http://docs.rancher.com/rancher/rancher-compose/)
You can also read more about the concept of adding services:

This link is in the link I directly sent you.

Also, I mentioned that there are many other sections within the “Rancher-Compose” section of the navigation bar, please try to look at them as they will answer many of your questions.
Here’s one of them that you are asking about.
