![]() While it is a best practice to use data volume container these days, providing persistent storage across multiple hosts for shared volumes seems to be tricky. If you think to put Docker Swarm into production in the actual state, I recommend to read Docker swarm mode: What to know before going live on production by Panjamapong Sermsawatsri. This should be supported by Rancher 1.2 which is not released yet.įrom this point of view it looks very reasonable that Docker Swarm in combination with Rancher (1.2) might be a good strategy to maintain your container farms in the future. Docker swarm seems to be evolving and is getting more nice features other competitors doesn't provide.ĭue the native integration into the docker framework and great community I believe Docker Swarm will be the Docker Orchestration of the choice on the long run. Usman Ismail has written a really good comparison of Orchestration Engine options which goes into details.Īs there is actually no clear defacto standard/winner of the (container) orchestration wars, I would prevent to be in a vendor lock-in situation (yet). ![]() This is great because this are all of the relevant docker cluster orchestrations at the market actually.įor the use cases, we are facing, Kubernetes and Mesos seems both like bloated beasts. Rancher describes themselves as 'container management platform' that 'supports and manages all of your Kubernetes, Mesos, and Swarm clusters'. Beside that it has many other great features. But the (first) great advantage: it can handle Docker Swarm. Portainer is pretty new and it can be deployed as easy as UI For Docker. It's pretty awesome and the best feature so far is the Container Network view, which also shows the linked container. Since some time there is UI For Docker available for visualizing and managing containers on a single docker node. Running Docker, which is actual the most preferred container solution, on a single host with docker command line client is something you can do, but there you leave the gap between dev and ops. How to update the base image(s) the apps are build upon and to test/deploy them?.How to provide persistent (shared) storage?.Which Orchestration Engine should be considered?.This is the point where operations is affected and operations needs to evaluate, if that might evolve into better workflow.įor yolo^Wdev Ops people there are some challenges that needs to be solved, or at least mitigated, when things needs to be done in large(r) scale. ![]() ![]() One of the benefits of containers is, that developer (in theory) can put their new version of applications into production on their own. I can understand that building and testing an application is important for developers. You will need to do this for all of the nodes in your cluster.įor more information on configuring imageRegistries in the cluster.yaml, please refer to cluster configuration API documentation.Since some time everybody (read developer) want to run his new microservice stacks in containers. Edit your file to apply the changes above and save the file. Go on to the nodes in your cluster directly, and edit your containerd configuration file /etc/containerd/config.toml. NOTE: You can also do this directly after your cluster is created and without running konvoy up. Enter the following command to check the contents of the containerd configuration file: $ cat /etc/containerd/config.toml Enter the following command: konvoy upĬonfirm the changes made to the cluster. For example, if your yaml file has password: $, password is set to the REGISTRY_PASSWORD value in your environment.Īpply the changes to your cluster. NOTE: You can use environment variables to specify imageRegistries values. spec.imageRegistries list in the cluster.yaml file.įor Konvoy, to add credentials for Docker Hub, set the options in your cluster.yaml as follows: kind: ClusterConfiguration Konvoy customers can configure their cluster to authenticate with registries (such as Docker Hub), and add registries, by defining each in the ClusterConfiguration.
