1. Create podman container using the docker mongo image: docker.io/library/mongo:latest
`sudo podman run -d --name mongod -p 27017:27017 -v /var/lib/mongodb:/data/db:Z mongo`

2. Create service file `/etc/systemd/system/mongod.service` to run container:

```
[Unit]
Description=MongoDB Podman container
After=network.target firewalld.service
Wants=network.target

[Service]
Restart=always
ExecStart=/usr/bin/podman start -a mongod
ExecStop=/usr/bin/podman stop -t 10 mongod

[Install]
WantedBy=multi-user.target
```

3. start container:
```
systemctl start mongod.service
systemctl enable mongod.service
```

4. Restore data to database: 
`podman run -it --rm -v $HOME/Downloads/sra:/tmp/sra:Z --network=host mongo mongorestore -d sra -c ncbi --gzip /tmp/sra/ncbi.bson.gz`

Is there a way to configure Replica set using podman in RHEL 8
