`nerdctl start` cannot start containers in `Created` or `Exited` status (`OCI runtime create failed: cannot allocate tty if runc will detach without setting console socket`)

[ghost]

Required behavior: Allow start Created or Exited containers, either with nerdctl start or nerdctl exec -it. Actual behavior: you can run a container, for example: nerdctl run -it nginx:latest --name nginx-container. You can stop it: nerdctl stop nginx-container. Issue: You cannot start again the container neither nerdctl start nginx-container nor nerdctl exec -it nginx-container /bin/sh. Error messages: nerdctl start nginx-container: FATA[0000] OCI runtime create failed: cannot allocate tty if runc will detach without setting console socket: unknown nerdctl exec -it nginx-container /bin/sh: FATA[0000] no running task found: task 0a88555b90488894c72918665b9b14bd6ae96e89676d65ca772b9abf34727884 not found: not found Environment:

-it is currently incomparable with stop/start, please use -d

It didn't work, I created and ran the container with nerdctl run --name my-container -d nginx, even modified the image to set the ENTRYPOINT to /bin/bash; the container exited immediately because there's no interactive nor tty attached, so there's no process to maintain running in background. Then, I tried to start or exec the exited container but got the following output: nerdctl start my-container: started the container but exited immediately due to the mentioned above. nerdctl exec -it my-container /bin/sh: FATA[0000] cannot exec in a stopped state: unknown, which is logical because we cannot execute commands on stopped containers.

I think in the meantime it cannot be achieve until the implementation of the create action from docker, because it allows us to define the -it parameters at creation time, then we can start the container in background allowing the interactive/tty connection for later.

+1 migrating from docker, very annoying nerdctl start -i <container> doesn't work after nerctl run -ti <image> /bin/bash .

[animatedcreativity]

Yes, cannot start stopped containers.

[raktim-sixt]

yes, same here...cannot start the container which is in the CREATED state

failed to create shim task: OCI runtime create failed: runc create failed: cannot allocate tty if runc will detach without setting console socket: unknown

has anyone found any workaround/solution to this?

[aerphanas]

is anyone know how to run image properly ? i run image with :

nerdctl run -it overlayfs@sha256:564f654982832faaeb09ab49b4b543b83a79f478b5d73bc2785fe0aa07648597

after i stop container and i want to run it again with :

nerdctl container start overlayfs@sha256:564f654982832faaeb09ab49b4b543b83a79f478b5d73bc2785fe0aa07648597

it say

FATA[0000] failed to create shim task: OCI runtime create failed: runc create failed: cannot allocate tty if runc will detach without setting console socket: unknown

i have version

nerdctl version 
Client:
 Version:	v1.0.0
 OS/Arch:	linux/amd64
 Git commit:	<unknown>
 buildctl:
  Version:	0.10.5
  GitCommit:	v0.10.5

Server:
 containerd:
  Version:	v1.6.9
  GitCommit:	v1.6.9
 runc:
  Version:	1.1.4

current solution : run container with -d flag

nerdctl run -d overlayfs@sha256:564f654982832faaeb09ab49b4b543b83a79f478b5d73bc2785fe0aa07648597

i don't know why it immediately stop the container if you run nerdctl ps -a it will have status Exited (0) even after add --restart flag it will restarting in loop, btw you can start container with command :

nerdctl start -a overlayfs@sha256:564f654982832faaeb09ab49b4b543b83a79f478b5d73bc2785fe0aa07648597

but it will give you blank shell, if you type ls it will response :

ls
bin
boot
dev
etc
home
lib
lib64
media
mnt
opt
proc
root
run
sbin
srv
sys
tmp
