Worker : invalid mount config for type

[Aalnafessah]

Hi Thanks for the instruction. When i type "docker service ps SERVICEID" i got this error : " invalid mount config for type ..." "No such image: singularities/…"

When i do the same this with master , i got this error: " invalid mount config for type ..."

Can you help ?

Can you share your docker version with me? To do that run following command docker --version

Also can you send the results of following command:

docker service ls

This is my docker version : Docker version 17.06.0-ce, build 02c1d87

docker service ls:

And this is the result of " docker stack ps spark_cluster ":

My docker version is 17.09.0. If you upgrade your docker, it may solve your problem. However, you can try following way before upgrading the docker.

First of all, run following command on each worker node

docker swarm leave

Secondly, on manager node

docker service rm spark_cluster_worker docker service rm spark_cluster_master

Then, run on manager node:

sudo docker stack deploy --compose-file=docker-compose.yml spark

After running the command above, check status of installation. If it is completed, add again worker node to the cluster(you can find necessary command to do that in installation guideline).

Then ,

sudo docker service scale spark_worker=

I hope, it will solve your problem

Thanks for your response. After i type "docker stack deploy --compose-file=docker-compose.yml spark" i got this message "Ignoring unsupported options: links "

I am not sure way !!!

Ok there is no problem. Now, you add worker nodes to the cluster(I have mentioned that how can you do that in installation guideline). After that, run following command

sudo docker service scale spark_worker=5

If you want to check your cluster situation, run following command

docker service create \ --name=viz \ --publish=8081:8080/tcp \ --constraint=node.role==manager \ --mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \ dockersamples/visualizer

It will provides an interface to watch the situation of your cluster

Now, open browser and check

I have done what you have said. I have done the following : For each worker node: "docker swarm leave". For Master node "docker service rm spark_cluster_worker" "docker service rm spark_cluster_master"

This what i get after workers leaved :

Then i have added tow workers node to the swarm:

Then i have run this command to scale workers to 4 :

This is the final result:

The same error which is ( invalid mount config for type…) any suggestion to overcome the problem?
