how keep srun container alive for a long time

Hi experts,
will the container launched by following way exit immediately after it execute the command '/etc/os-release'

`$ srun --container-image=centos grep PRETTY /etc/os-release
`
`PRETTY_NAME="CentOS Linux 8"`
if so, how can I do the the setting in the container if I want? is there any way to keep it interactive ?
