Unable to access webui of confd inside docker hosted on a CENTOS

We have a docker hosted on a CENTOS machine.

The docker runs a copy of confd, in whose configuration file we have set the webui tag enabled at port 8008.

When we finally run confd on the docker, I get an error “Module “tailf-webui” in access rule “any-group/tailf-webui-user” does not exist - ignoring rule”.

Also, when I try to access the webui from the CENTOS browser using docker-ip:8008 I don’t get a thing.

I need to see the webui before I proceed further.

Any help please?

Hi Swateek,

Do you have the module tailf-webui in the load path of ConfD?

You can verify this by running the command: confd --status

An example output is: (I highlighted what you need to look for)

confd --status

Hey Nabil,

I don’t see it in the load path, even if the webui tag inside the confdrc.config is set to “true”.

This makes me think you are using the Basic ConfD version that doesn’t come with the WebUI support.

Can you confirm the ConfD version that you encountered this issue with?

(under the ConfD install directory)



confd --version

The version is 6.0

I don’t think this is a version problem, if this version hadn’t supported the webui feature, then it would never have that tag in the configuration file itself.

Any thoughts on this?

The configuration in the ConfD configuration file, confd.conf, in some examples do have the WebUI tag as the same example is shipped with ConfD Premium too.

But the JSON-RPC API and the auto-rendered WebUI examples are removed from the ConfD Basic version. So are SNMP, REST, CLI customization, a couple of CLI styles, CLI multi-session, and Java and Python language bindings.

In ConfD Basic, NETCONF is the focus. A limited CLI, and MAAPI are enabled too, for debugging purposes and to enable real applications to be built with NETCONF support. You have C and Erlang language bindings to choose from to interact with ConfD for your application through for example the CDB, MAAPI, and DP application interfaces.

Thanks cohult, I’ll upgrade it to a higher version.

If they hadn’t shipped with those things which aren’t part of the distribution would have saved a lot of development time.

Thank you for your time!
