Toolbox: casa no en contenedor

¡Hola @FlorianLudwig! ¿Es posible que vuelva a reproducir el problema con todos los pasos? Me gustaría ver la salida detallada ( --log-level debug ) de los comandos toolbox create y toolbox enter . Además, me gustaría ver el resultado de podman logs <name-of-container> después de que intente ingresar al contenedor.

Claro aquí tienes:

$ toolbox create f31 --log-level debug --image fedora-toolbox:31

¡Gracias por los registros, @FlorianLudwig! Me las arreglé para reproducir este problema sin siquiera intentarlo, pero mi escenario es un poco diferente porque uso Silverblue donde una carpeta de inicio ( /home/<insert-name> es un enlace a /var/home/<insert-name> ). Logré evitarlo ingresando primero al directorio /var/home y luego tratando de ingresar al contenedor. Esto es muy extraño e intentaré investigar un poco más.

Estas líneas de toolbox enter ... son raras:

DEBU Looking for command /bin/bash in container f31 
Error: exec failed: container_linux.go:349: starting container process caused "exec: \"sh\": executable file not found in $PATH": OCI runtime command not found error
DEBU command /bin/bash not found in container f31; using /bin/bash instead

¿Cómo puede /bin/bash no estar en el contenedor? ¿Estabas en medio de algunas transacciones de RPM?

@debarshiray No toolbox create f31 --image fedora-toolbox:31 para crear el contenedor)

Yo no creé la imagen. Creo que esta imagen fue creada
por los autores de la caja de herramientas

Sé. Por eso me sorprendió. :)

¿Podría montar el sistema de archivos del contenedor y echar un vistazo si realmente falta Bash?

$ podman unshare -- /bin/bash
# container_root=$(podman mount f31)
# ls -l $container_root/bin/bash
...
# ls -l $container_root/usr/bin/bash
...

@debarshiray

luce bien para mi:

@FlorianLudwig , ¿el problema sigue presente? A pesar de que hice algunas investigaciones, no pude encontrar al culpable.

@HarryMichal
Ya no puedo reproducir esto con

toolbox --version
toolbox version 0.0.95

Por eso lo cierro.
