/Update NerdCTL on RancherDesktop macOS

Created Thu, 03 Feb 2022 10:46:56 +0000


So you are already using RancherDesktop and NerdCTL from the betas congrats, but you want to use the multi-platform build

so you need to update Rancher and Nerd, well thats where the issue exists, Lima doesnt update NerdCTL automatically so you need to update your instances version


First you need to get into the instance

LIMA_HOME=/Users/<username>/Library/Application\ Support/rancher-desktop/lima \
	/Applications/Rancher\ Desktop.app/Contents/Resources/resources/darwin/lima/bin/limactl \
	shell 0 sudo --preserve-env=CONTAINERD_ADDRESS sh

Now that your in the instance, you need to update NerdCTL

I always make a copy of the original version just incase

cd /usr/local/bin/
cp nerdctl nerdctl-old

Now update nerdctl the download is different on M1 so go to NerdCTL Releases and choose the latest one

cd /usr/local/bin
wget https://github.com/containerd/nerdctl/releases/download/v0.16.1/nerdctl-0.16.1-linux-amd64.tar.gz
tar -xf nerdctl-0.16.1-linux-amd64.tar.gz
rm nerdctl-0.16.1-linux-amd64.tar.gz

Now if you go onto a seperate terminal and do nerdctl -v you should now have the latest version of NerdCTL installed

Something to remember

If you are using NerdCTL to build multi-platform images, then remember to add --all-platforms to your push command
