dockershim dockershim 是 Kubernetes 的一个组件,主要目的是为了通过 CRI 操作 Docker。Docker在 2013 年就出现了,2014 年 Kubernetes 发布并默认使用 Docker 作为容器运行时,而 dockershim首次正式出现是在 2016 年。Docker 在创建之初并没有考虑到容器编排或者是考虑 Kubernetes,但 Kubernetes 在创建之初便采用Docker...
The Kubelet speaks CRI natively to the engine (or a shim like Docker shim), while humans can use the CRICTL tool. If you haven’t heard of CRICTL, check this article. Pulling/Expanding images to disk This is a two part process. First, the container engine has to pull the images ...
This was always something of a hack, however, and earlier this year, Kubernetes jettisoned support for Dockershim. (Podman, by contrast, uses the compatible CRI-O runtime from the Cloud Native Computing Foundation.) This is part of a larger story about Docker trying and failing to become an...
The short answer is no. In the past, Kubernetes included a bridge called dockershim, which enabled Docker to work with CRI. From v1.20 onwards, dockershim will not be maintained, meaning that Docker is now deprecated in Kubernetes. Kubernetes currently plans to remove support for Docker entirel...

Was Docker runtime a bad choice, always? One of the answers to the news is that nobody should have ever used Docker runtime in the first place, because it was never compatible with the CRI API and it required a proxy (shim for API translation) to make it work with Kubernetes. For ...
CRI-O, respectively. Practically, this means that Dockershim, the tool that Kubernetes currently needs to use containerd, will be removed in either 1.22 or another release next year. Related to this, the status of the CRI API, which has to date been in alpha,continues to be advancedas ...
It turns out that Docker images frequently have broken timezone setups. This usually results in a warning that the configuration is wrong, or that the timezone offset doesn't match the found timezone. The easiest way to fix that is to set a TZ variable in your docker setup to whatever ...
Threads are also missing from Preview 2, and work on that is still ongoing.One neat thing of the way WASI is structured is that virtualization layers can be nested. In order to make upgrading between WASI versions easier, a shim, a shim will be provided which allows Preview 1 code to ...
