On Linux you should be able to downgrade to the desired version easily, but if you use Docker for Mac or Docker for Windows, and have already updated to 17.12, because the client urged you to, that might be an issue. Docker does not provide links to the old versions. Thankfully, there are reliable workarounds. Older Docker for Mac versionsDocker Desktop is an application for MacOS and Windows machines for the building and sharing of containerized applications and microservices. Docker Desktop delivers the speed, choice and security you need for designing and delivering these containerized applications on your desktop.Docker for Mac has had an open issue since July 3 - Docker fails to launch on Apple Silicon #4733Docker EE/CE 17+ Docker for Mac/Windows has added a config editor to the tray icon UI to allow editing of Dockers daemon.json file that will be persisted in the VM.
Docker 17.12 How To Ensure YouThe caveat of course is that you'll have to use ARM containers, and to be honest Docker's manifest system has always confused me somewhat - it seems like a wild west when it comes to how to ensure you end up with an ARM image on your ARM box, some publishers use tags, some use completely separate repos, and some use manifests, and if you don't get it right it's way too easy to end up with an x86 container on your ARM host, while you scratch your head trying to figure out why your stack won't startup.And of course there's still some apps out there, mostly closed source, with no ARM build (e.g. MS SQL Server or OracleDB). The Docker for Mac VM is based on Alpine Linux. The init system is based on OpenRC.Now this is completely understandable, as according to the comments the Apple DTK lacks support for virtualization.Basically, Docker Desktop for Mac does not need the VirtualBox, but this tutorial will create a virtual machine using by VirtualBox.Currently it is not possible to change the version of k8s in Docker desktop. This is expected right now (and indeed there's nothing we can do about it yet) as the new chips don't have virtualisation support yet.If Docker says Docker for Mac is not functional yet on Apple Silicon - What was Apple showing us in the presentation?In the background you can see they show a running Docker for Mac control panel - complete with some running containers.Was this a simulated Docker for Mac window for the presentation? If so it seems pretty misleading and makes me question everything else that was shown.Anyone with a DTK have thoughts on this? Did I miss a part of the presentation where they mentioned anything about it?Docker for Mac has basically always used Linux in the background, it just spins up a Linux VM to run your containers (changing the resource allocations in the Docker control panel is essentially adjusting the parameters for that VM). AFAIK there's no plans to implement "native" macOS containers (maybe just low demand, although I can see some definite use cases for CLI tools that are Mac-only, e.g.If you need to build containers on your laptop and you want minikube to pull them form your laptop rather than a remote container registry you will benefit from running Docker desktop since it includes a local container registry.How do you manage local development dependencies?If your application depends on commonly used OSS databases, message queues, caches you will have to decide how setup these dependencies on your laptop. By default it will try to resolve container images from Docker hub and other public registries. For example, minikube start -kubernetes-version=v1.18.3 will launch k8s 1.18.3If you use a Dockerfile during development you will need to have Docker desktop installed, otherwise you won’t be able to run docker build to create a container image on your laptop.If you are building your container image using tools such as JIB that don’t require a local Docker daemon you can run minikube without Docker desktop.Minikube does not ship with a container registry. You can pass minikube a command line argument to launch a specific version of k8s. Basically Docker is shipping the “most stable, widely used” version of k8s since many organizations run the oldest GA version of k8s in production.Minikube supports the most recent GA version of k8s plus the previous 6 minor versions. ![]() You need to pick a specific version of Kubernetes to work with Your developers are only on MacOS and Windows. The version of Kubernetes included in docker desktop is the version you want to use You are using test containers with junit You are managing your local development environment with docker compose
