Test the connectivity to a Docker registry before creating it

[kwerle]

I tried to configure a private registry using the host url I docker log'ed in to - which was like

https://my.host.name/v2/

It turns out that portainer didn't like that, but gave no immediate feedback. Instead it said:

"Image from container: invalid reference format"

when I tried to add a new container.

I recommend that when you add a registry portainer tries to validate it. If that's not possible then it'd be nice for the failure message to be way more explicit. Maybe including some technical error information.

You should probably try with https://my.host.name instead of https://my.host.name/v2/

I agree, we will try to test the connectivity before creating the registry.

[kwerle]

Yes, that is the fix. My point was that it wasn't clear what the issue was. A connectivity test would have nailed it at registry creation time - if that's possible... Thanks!

i got the same issue
my setting was like below
Registry URL https://njdocker1.nj.thundersoft.com
name harbor

then i want to use pull image
name njdocker1.nj.thundersoft.com/public/rsyslog:1.0
Registry harbor

i was setting the auth info and if i use docker pull njdocker1.nj.thundersoft.com/public/rsyslog:1.0 can pull the img from my own Registry

@deviantony this is my origin setting

You need to add the port number to the registry url... port 5000 is Docker default..

@ncresswell ths but we use harbor ,the default port was 80.but even add the port it still does't work

throw "Failure:invalid reference format""

[deviantony]

@zwx168238 are you using njdocker1.nj.thundersoft.com as the registry URL and public/rsyslog:1.0 as the image you pull ?

[zwx168238]

@deviantony i use njdocker1.nj.thundersoft.com/public/rsyslog:1.0 as the image,it was the full path

[deviantony]

@zwx168238 you need to create a registry first using njdocker1.nj.thundersoft.com and then select that registry when creating a container / pulling an image and use public/rsyslog:1.0 as the image name.

[zwx168238]

@deviantony actually i was do like this

[deviantony]

@zwx168238 and this is not working? Feel free to ping me on Slack to discuss this.

[zwx168238]

[asasmoyo]

Hello! I would like to start my contribution to here. If no one working on this, I would like to take it :)

[deviantony]

@asasmoyo Nobody is working on this yet, feel free to open a PR :-)

[asasmoyo]

Great :)
I am thinking to do http request to URL/v2 (with auth if it is present) then check wether it returns 200. Do you think is it enough to just do this?

[deviantony]

@asasmoyo yes, that should be enough for a check.

[asasmoyo]

@deviantony please take a look my pr
