to avoid any naming conflicts with any other instances of Kubernetes you may have running. We use octopus in our CI/CD pipeline to deploy our projects to machines. How can we improve it? A Deployment runs multiple replicas of your application and automatically replaces any instances that fail or become unresponsive. It supports both a max number or percentage of pods to be unavailable during an update, as well as a max number of new pods that can be created. So why use rolling deployments over other patterns such as canary or blue/green? Hint: This allows connections to a service to finish naturally and prevents new connections from being established. The second step creates and pushes the Docker image … Ask Octopus - Can I host the Octopus Server in Docker? Further deployments won’t start until a previous deployment has finished. We feel this best follows the container mentality and avoids trying to re-invent container build and orchestration tools that already exist. It does this by creating a new pod and destroying the old ones after it has completed. Attempting to access the dashboard remotely requires you to jump through a few hoops. Kubernetes vs Octopus Deploy: What are the differences? Docker - the open-source application container engine - OctopusDeploy/docker If we run the create deployment command: MicroK8s will create our deployment and confirm it has been successfully created. Is there anything we can do to improve it? Lastly, it’s definitely a good idea to test your rollback strategy frequently. This is an area that the Docker and Windows team are actively improving. CI/CD pipeline guides What works – local macvlan. Cannot sign-in to Octopus Deploy after docker installation. Open the URL in a browser, and we can see that we have v0.0.1 for our application running in Microk8s: Let’s go ahead and instruct Kubernetes to update our three pods with v0.0.2 of our image octopusdeploy/rolling-deploy-web-example by running the set image command: Next, we can watch the live progress of our rollout until its complete by running the rollout status command: You can see it indicated it was updating one Pod at a time. While Docker Containers on Windows Server (not Docker for Windows through Docker Toolbox) are now generally available, this feature appears to still have some issues with key areas such as networking. To find out more about Kubernetes, my colleague Shawn continued his container series focussing on Kubernetes. The first step deploys the NuGet DockerWebAppDemo package to a custom location in the Pivot Machine (with the Docker Machine role). Deploy a stack to a swarm Estimated reading time: 7 minutes When running Docker Engine in swarm mode, you can use docker stack deploy to deploy a complete application stack to the swarm. Typically, a service is a small piece of a much larger architectural picture and is popular with microservices. This is the command-line interface (CLI) for managing Kubernetes. We can do this in a condensed one-liner: This locates our container by the image name octopusdeploy/rolling-deploy-web-example:0.0.1 and passes that to the stop command, and finally passes that to the rm command. Database rollbacks sudo docker swarm init: This will initialize your current node as a swarm manager. To do that, we run the expose command: Although the rollingdeploy-microk8s pod has been created, it might not be available immediately. We use analytics cookies to understand how you use our websites so we can make them better, e.g. In the mean time the new version 15 (Octopus) was released. I would use Octo to deploy your images onto target machines. "Multi-container descriptor" is the primary reason why developers choose Docker Compose. We will use the Octopus out-of-the-box features to deploy the DockerWebAppDemo package to the Pivot Machine, and the new step template to create and push the Docker image to DockerHub. Google describes Kubernetes deployments as items which: represent a set of multiple, identical Pods with no unique identities. Analytics cookies. Performing rolling deployments which involve some kind of persistent storage can be tricky, though not impossible. We didn’t build Octopus for “publish to production from your IDE” demos – we built it for the real world. No matter which tooling you use, rolling deployments is just one pattern available to optimize deployment of your software. A script to remove the node from the load balancer. To demonstrate the different approaches to rolling deployments, we have a very simple .NET Core 3.1 application which will display a web page. The ultimate guide to rolling deployments, Kubernetes containerized application setup, After the first node has updated successfully, proceed with draining the remaining node still running, Ubuntu 18.04 LTS or 16.04 LTS (or other OS that supports. A random port, in the range 30000-32767 (by default) will be assigned by Kubernetes as we chose a NodePort type when we ran the expose command earlier. We review your answers every month to find ways to improve these docs. By performing this action, instances which are selected to be updated, can be removed from the available pool after they have finished their work, while others remain online serving traffic. While deploying a Windows Container to a Tentacle target on Windows should work, you may experience issues trying to use custom networks or volumes. Octopus Deploy vs Rancher: What are the differences? 9 min read Save ... Ryan Rousseau for Octopus Deploy. The Octopus Project will look like: The first step deploys the NuGet DockerWebAppDemo package to a custom location in the Pivot Machine (with the Docker Machine role). Next, we’ll set the application pods to listen on port 5001. In addition to this, Kubernetes has a handy built-in feature to allow updates to be reverted to a previous version. Docker run/stop paved the way for things like compose/swarm but you can't use it for building the entire platform. The Octopus concepts of feeds, packages and versions can be mapped to the Docker concepts of registries, images and tags. Docker swarm: Can only deploy applications as microservices. Feel free to leave a comment, and let us know what you think about rolling deployments! they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. Before you install MicroK8s, it’s worth noting that there are some prerequisites: To install MicroK8s, we run the snap install command: Full install output ... All of the other containers run on Linux, but Octopus Deploy only runs on Windows, so I need to assign it to another host (Windows Server 2016 running inside VirtualBox). Docker Compose, Octopus Deploy, Kubernetes, Rancher, and Docker Swarm are the most popular alternatives and competitors to kubernetes-deploy. In our example we only use a few deploy options, but it is worth diving in the documentation since here lies the greatest power of Swarm. If you prefer not to use sudo when executing your commands, be sure to follow the Docker post-install instructions. The Kubernetes tutorial on updates includes a nice diagram showing how it works: Just as before, I’ll re-use our pre-built container image for this demonstration, this time using MicroK8s. Octopus Deploy is the first platform to enable your developers, release managers, and operations folks to bring all automation into a single place. When deploying new versions of modern software, like web applications and services, it’s still common for some teams to take their entire website down while they do deployments. We feel however, that Octopus Deploy … Kubernetes: Kubernetes offers an in-built monitoring system for all of its processes & services. We can scale our deployment directly from the dashboard by clicking on the three ellipsis on the right hand side of the Deployments section: For our Kubernetes deployment, I updated the Desired Replicas to 3 so I can perform a rolling update and then hit Scale: Equivalent kubectl commands Then it's just a matter of running docker-compose up and we get our awesome website:. Octopus Deploy - A single place to release, deploy and operate your software. You want the docker-compose.yml to be either in source control or managed by octopus but essentially octopus to be issuing the docker compose up. I’m running Docker on an Ubuntu server and using our pre-built container image. There are a couple of ways to install Docker on Ubuntu: I opted for the Ubuntu repository as it seemed quicker and easier, but your mileage may vary. With the use of child steps, we can set-up our deployment process for the rolling-deploy-web-example application in Octopus. Silo’s break down, collaboration begins, and your team can ship – and operate – … For scaling our resource, that is: After the pods have been provisioned, we can confirm this by querying the pod’s status directly by running the get pod command (names may vary): To verify our application is working, we need to find the port that has been exposed by Kubernetes to the deployment we created at the start by running get service: In my case, the port is 32334 so my URL to access my service is: Note: The main reason we have chosen Kubernetes over Docker Swarm is related to the following artifacts: Key features: Easy and flexible installation, Clear dashboard, Great scaling operations, Monitoring is an integral part, Great load balancing concepts, Monitors the condition and ensures compensation in … Today, users expect applications to be available all the time, and there are a few deployment patterns you can use to achieve zero-downtime. If you need any additional help configuring your CI/CD pipeline, we have created the Octopus Guides which include step-by-step instructions to setup CI/CD pipelines for various technology stacks, including Docker and Kubernetes. Now that we know our website works, we want to deploy it via Octopus Deploy … Containerization — Docker, Rocket, Unik; Orchestration — Kubernetes, Swarm, Mesos; Software deployment — Elastic Beanstalk, Octopus, Vamp; Measurement — Datadog, DynaTrace, Kibana, NewRelic, ServiceNow; Canary Releases. As with Docker, it’s important to understand what will happen with any databases you have when you initiate a Kubernetes rollback. This uses Docker Swarm as its orchestrator under the hood. Deploying Through Octopus. Posted on 12th October 2020 by mnsasha. Finally, to remove our Docker service we just run the rm command: As you can see, it doesn’t take much setup to get rolling deployments working in Docker. I’ll also provide you with some practical examples of how to implement rolling deployments with different tooling. Well, rolling deployments offer the following benefits: New versions of your application are rolled-out incrementally. A typical process looks something like this: If you want to ramp up your rolling deployment and deliver a new version to more than one node simultaneously, say two for example, then it would look like this: This incremental approach is often favored in web applications which sit behind a load balancer, as most load balancers support a concept known as Connection draining. Rollback, you can rollback anytime you want to perform a rolling update first. Improve it by the swarm is n't built to be issuing the Docker and Windows team actively.
