Im wondering as to how to start a mongodb replica set using the new Docker 1.12 swarm mode service model. starting a service allows you to specify a number of container replicas, which in the minimal replica set case would be 3. but how would then parameters be specified for the replica set primary, if […]
Suppose you have two services on your topology API Web Interface Both suppose to be running on port 80. On docker swarm when you create a service if you wanna to access it outside the cluster you need to expose and map the port from the service to the nodes (external ports). But if you […]
I’m new on docker swarm. I’d like to know how to configure this tool to start with a minimum number of nodes and grow to a maximum number of nodes when it is required. Should I use another tool or can docker swarm solve this for me?
I created a docker swarm cluster with 4 nodes out of it 2 is swarm manager (swarm supports multiple manager) I understand if the current manager node goes down then the second manager takes the role of being the swarm manager. In my case I am firing the rest call to the swarm manager for […]
We are trying to run a simple pipeline distributed on a docker swarm cluster. The luigi workers are deployed as replicated docker services. They start successfully and after a few seconds of asking for work to luigi-server, they begin to die due to no work was assigned to them and all tasks end up assigned […]
Currently I have a bunch of RHEL7 VMs running on RackSpace and want to deploy docker swarm for testing purpose. The Docker Docs only describes the method to deploy docker swarm by using docker machine. Question: Since VirtualBox cannot be used in VMs, are any other ways such that I can directly deploy docker swarm […]
Does anyone know how (if possible) to run docker-compose commands against a swarm using the new docker 1.12 ‘swarm mode’ swarm? I know with the previous ‘Docker Swarm’ you could run docker-compose commands directly against the swarm by updating the DOCKER_HOST to point to the swarm master : export DOCKER_HOST=”tcp://22.214.171.124:3375″ and then simply execute commands […]
I am finding docker swarm, kubernetes quite similar and then there is docker which is a company and the above two are docker clustering tool. So what exactly all these tools are and differences between them?
I have spent the past few day working on creating a docker swarm on Digtital Ocean. Note: I don’t want to use -link to communicate with the other apps/containers becasue they are technically considered deprecated and don’t work well with docker swarm (i.e. I can’t add more app instances to the load balancer without re […]
I’m trying to deploy my container to docker swarm cluster(docker engine 1.12.1). The features of docker swarm mode really are exciting, such as clustering docker, multi-host networking. However I find something can’t be archived in swarm mode so far(docker 1.12.x), which works well when using docker run to start container. My host has eth0 for […]
