kenwoodjw / docker-load-and-push.sh
Created December 13, 2022 10:11 — forked from stefanvangastel/docker-load-and-push.sh
Bash scripts to pull, (optional) retag, save, load and push Docker images. Created to provide easy means to download an image, retag it to use a private registry and then save it to an external disk. In a offline or on-premise environment you can use the load and push script to load images and push them to a private registry.
#!/bin/bash
#### Functions ###
display_usage() {
echo "This script must be run with Docker capable privileges and you should login to your registry before pushing!"
echo -e "\nUsage:\n$0 <saved_image> [--push]\n"
echo -e " <saved_image>\t\t\tThe image file to load and push"
echo -e " [--push]\t\t\tPush to registry"
echo -e "\nExample: $0 /mydir/ubuntu.tar --push "
}

[root@ip-11-0-0-239 centos]# firewall-cmd --zone=trusted --add-source=94.204.104.194/32
success
[root@ip-11-0-0-239 centos]# firewall-cmd --zone=trusted --add-source=94.206.104.194/32
success
[root@ip-11-0-0-239 centos]# firewall-cmd --zone=trusted
success
[root@ip-11-0-0-239 centos]# firewall-cmd --list-sources
You're performing an operation over default zone ('public'),
but your connections/interfaces are in zone 'trusted' (see --get-active-zones)
You most likely need to use --zone=trusted option.
