Docker rabbitmq image error when building “Unable to perform operation on node”

[victo...@gmail.com]

I am having an error when trying to build image with:

docker-compose build

Error:

------------------------------------------------------------------------------------------------

docker-compose.yml file:

-----------------------------------------------------------------------------------------------

version: '3'

services:

  rabbitmq:

    build: './rabbitmq'

The error says that the node is not running, but I have not seen anything about starting a node in the documentation. In all the tutorial I looked at this should work.

Thanks everyone

Hi,

The error says that the rabbitmq node is not running.

This may be caused by `sleep 10;` in the docker compose command. I'm not sure why this sleep is there but you can try to remove it or go around it somehow.

By the way, there is a way to specify a different default user and password using environment variables, if that's what you're trying to do.

Also management plugin is supposed to be enabled if you use the 3-management image.

Hope this helps.

Hi Daniil,

- The sleep 10 and the eneable management plugin was something I forgot to remove, thanks for that.

- I am not trying to specify default users, I am trying to create new ones after rabbitmq is install and started in the container.

- This is my latest version, but the result is the same and now I start rabbitmq manually

dockerfile:

FROM rabbitmq:3-management

Thank you very much!!

Your code races with RabbitMQ startup.

Use `rabbitmqctl await_startup --timeout <seconds>` or `rabbitmqctl await_cluster_nodes <count> --timeout <seconds>` or [2] to await for node startup.

See server logs to get some details on the timing of node startup.

A better way to preconfigure a node is via definition import [1].

Hi Michael,

I have tried that but...

I can not run that command also so I think the problem may be other, maybe due to some restrictions in the rabbitmq image

Thanks

I hope you can see the image, opening it in a new tab and making zoom, if you can not I will write it.

I do not know if this is normal but if I do not start rabbitmq-server in background(line 13), rabbitmq start well but the image never finish building. Is this normal?

[Daniil Fedotov]

It appears that rabbitmq-server runs in foreground. You can run it in background and use $! to access its pid and wait for it using 'rabbitmqctl wait' command:

This command should do the trick:

rabbitmq-server & rabbitmqctl wait --pid $!

[Victor]

I run it in background, I have only ran it in foreground once(my previous post) just to show you that the rabbitmq-server command never ends. It stays forever as shown in the previous snippet.

Thanks for the help

The message says that the node is not running. It can take more than 30 seconds for a node with existing data directory to start.

I highly recommend inspecting server logs over guessing. If a node fails to start because e.g. its critically important paths

are not configured or not readable/writeable (such as the node's data directory), it cannot possibly start and thus await_startup cannot

possibly return successfully.

Guessing is very expensive. Collect data instead.

As I did not found the error, I made it the other way you told me.

Dockerfile:

FROM rabbitmq:3.6.6-management

MAINTAINER victo...@gmail.com

ADD rabbitmq.config /etc/rabbitmq/

RUN chown rabbitmq:rabbitmq /etc/rabbitmq/rabbitmq.config
CMD ["rabbitmq-server"]

rabbitmq.config:

[
  {rabbit,
    [
        {default_vhost,<<"/">>},
        {default_user,<<"hyper">>},
        {default_pass,<<"hyperpass">>},
        {default_permissions, [<<".*">>, <<".*">>, <<".*">>]},
        {default_user_tags, [administrator]}
    ]
  },
  {rabbitmq_management,
    [{listener, [{port, 15672}]},
        {http_log_dir, "/var/log/rabbitmq/management_http.log"}]
  }
].

I hope this helps others

Thank you Daniil and Michael (:

[Michael Klishin]

I'm not 100% sure what specifically you did and it is a true shame that you have to use a version with known issues (3.6.6) from November 2016

but thank you for reporting back to the list :)
