docker-swarm

Docker Swarm can manage two types of storage: volume and bind. While bind is not suggested by Docker Documentation since it create a binding between a local directory (on each swarm Node) to a task, volume method implementation is not mentioned, so I don't understand how volumes are shared between tasks. How Docker Swarm shares volumes between nodes? Where are volumes saved (on a manager? and if there are more than one manages?)? There is no problem between nodes if it runnings on different machines in different net? Does it create a VPN? What you're asking about is a common question. Volume

I'm looking for some pros and cons of whether to go with Marathon and Chronos, Docker Swarm or Kubernetes when running Docker containers on DC/OS. For example, when is it better to use Marathon/Chronos than Kubernetes and vice versa? Right now I'm mostly into experimenting but hopefully we'll start using one of these services in production after the summer. This may disqualify Docker Swarm since I'm not sure if it'll be production ready by then. What I like about Docker Swarm is that it's essentially just "Docker commands" and you don't have to learn something completely new. We're already

My environment: Ubunut 17.04 LTS npm --version: 5.6.0 nodejs --version: 4.7.2 angular cli version: 1.6.4 docker-compose file: version: '3' services: my-app: build: context: . dockerfile: Dockerfile restart: unless-stopped volumes: - .:/usr/src/app ports: - "4200:4200" I commented out the EXPOSE 4200 in dockerfile because I'm already mounting it from docker-compose.yml file, is that NOT ok, should I expose in dockerfile and mount in docker-compose? Running npm start on command line launches the app successfully on the browser as I'm able to go to localhost:4200 and see the app running. However,

I am already familiar with docker/swarm , but find there occurs a "new" project: docker/swarmkit . But unfortunately, after reading the README , I still can't figure out what is the function of docker/swarmkit . Could anyoone help to elaborate the relations between docker/swarm and docker/swarmkit ? Why is docker/swarmkit born? Docker Swarm is an older (2014) Docker native orchestration tool. It is standalone from the Docker engine and serves to connect Docker engines together to form a cluster. It's then possible to connect to the Swarm and run containers on the cluster. Swarm has a few

Initialize swarm mode: root@ip-172-31-44-207:/home/ubuntu# docker swarm init --advertise-addr 172.31.44.207 Swarm initialized: current node (4mj61oxcc8ulbwd7zedxnz6ce) is now a manager. To add a worker to this swarm, run the following command: Join the second node: docker swarm join \ --token SWMTKN-1-4xvddif3wf8tpzcg23tem3zlncth8460srbm7qtyx5qk3ton55-6g05kuek1jhs170d8fub83vs5 \ 172.31.44.207:2377 To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions. # start 2 services docker service create continuumio/miniconda3 docker service create --name redis

There is something that I am not getting when developing an application while using docker containers. Lets say I am developing a java application and I set up a java container with jdk 8 base image, I still need to install java 8 jdk on my local development machine, since the IDE which I am going to use is going to look for runtime libraries on the local machine not the docker container. Is this right or am I missing something? Somethings I will be able to do entirely on the docker container like setting up a database but some things I will also have to do on my local development machine and
