When I fixed the script issue for myself on mac, it did not fix the certificate issue. I am still trying to figure out how to fix that.

@Imran489 Thanks for the information. I'll check it out in a few days. 🤔

Hi @Imran489 , that's not the same problem with this issue.

It seems the issue is caused by the container runtime, and Chaos Mesh does NOT support Windows now, and Windows Support is not on the roadmap.

I am going to close this issue now.

If you still face the same issue with contained, fell free to create a new issue.

If you think the problem is still similar to the bash syntax problem, feel free to reopen it! Thanks!

Also cc @g1eny0ung
