Sensu Client doesn't start about docker-sensu

[sstarcher]

The template for the client.json is located here - https://github.com/sstarcher/docker-sensu/blob/master/templates/client.json.tmpl

I would recommend running the container and changing the entrypoint to /bin/sh so you can run the start command yourself and capture the client.json to verify that it's valid.

If you don't intend to use the template that this container provides I would recommend overwriting it with your file ./client-conf/client.json:/etc/sensu/config.json"

[sstarcher]

Looking at the docs the template requires

CLIENT_NAME *no default*
CLIENT_ADDRESS *no default*

I did override it. Check the volumes section under the client definition in the docker-compose.yml file. Is this what you mean? Thanks!

• "./client-conf/client.json:/etc/sensu/config.json"

[sstarcher]

Close, but not correct.
You overwrote /etc/sensu/config.json not /etc/sensu/conf.d/client.json

[Northwood128]

Ok ,I did that and I still get the same error. Not only that, the file I mounted on /etc/sensu/conf.d/client.json gets changed by this:

{
  "client": {
    "socket": {
      "bind": "127.0.0.1"
    },
    "name": "51f83f494049",
    "address": ,
    "deregister":  true,

    "subscriptions": [

        "all"

        ,"default"

    ],

    "keepalive": {
      "thresholds": {
         "warning": 120,
         "critical": 180
      },
      "handler": "default"
    }
  }
}

{"timestamp":"2017-06-25T14:48:49.358825+0000","level":"fatal","message":"config file must be valid json","file":"/etc/sensu/conf.d/client.json","error":"unexpected comma at line 7, column 17 [parse.c:575]"}

It looks like its not letting me use my own config file and instead it wants me to set all those env variables. Was it supposed to be like that?

[sstarcher]

Looks like it blindly processes the templates.

• You can either try and set the 2 values it wants and let sensu merge your configuration file in addition to the default config.
• You can replaced the original template with your file and it should copy it to the correctly location.

I'm gonna try to create a new client definition using only environment variables and I'll let you know how it goes.

[sstarcher]

If you set the 2 required variables it should merge your file with the templated file.

[Northwood128]

Confirmed. You have to set up those variables in the docker-compose.yml file. You can't just use a configuration file. Thanks! It works now.

[amirhmi]

I have the same problem and error .

But I don't get what you did for this purpose.

Can you tell me how you made that work?

[arecalde-edrans]

Hi @amirhmi ! If you read above, you can see that what I did was set up those environment variables on my docker-compose.yml

CLIENT_NAME: 'something'
CLIENT_ADDRESS: '127.0.0.1'

[amirhmi]

Can I run that with docker run and only change env variables?

@arecalde-edrans

[arecalde-edrans]

Yeah. With -e

[amirhmi]

thank you very much
