How to delete container use containerd ctr?

I use sudo ctr container run ... to run a container. But there are something wrong with the process in my container. So I suppose that there is no task is running. I use sudo ctr task ls, it shows,

TASK         PID    STATUS
test    0      CREATED

Then I want to kill it with sudo ctr task kill test. However, it shows that

ctr: process not started: unknown

Then I use sudo ctr task delete test. It also shows errors,

ctr: task must be stopped before deletion: created: failed precondition

I don't know how to delete this container. Once I delete this container, it comes with ctr: task must be stopped before deletion: created: failed precondition. How can I delete this container?

I had the same challenge. Turns out in containerd ctr, tasks and containers are different things. According to this blogpost, a container is a metadata object that resources are allocated and attached to while a task is a running process in the system.

So, to answer your question, you can simply remove/delete the container by:

ctr container delete test

You can substitute delete with either del, remove or rm. They all do the same thing. That should get rid of your error

You can try this way.

ps aux | grep shim
sudo kill -9 <pid of your process>
