Usage:
  sealer run [flags]

Examples:

create cluster to your bare metal server, appoint the iplist:
	sealer run kubernetes:v1.19.8 --masters 192.168.0.2,192.168.0.3,192.168.0.4 \
		--nodes 192.168.0.5,192.168.0.6,192.168.0.7 --passwd xxx

specify server SSH port :
  All servers use the same SSH port (default port: 22)：
	sealer run kubernetes:v1.19.8 --masters 192.168.0.2,192.168.0.3,192.168.0.4 \
	--nodes 192.168.0.5,192.168.0.6,192.168.0.7 --port 24 --passwd xxx

  Different SSH port numbers exist：
	sealer run kubernetes:v1.19.8 --masters 192.168.0.2,192.168.0.3:23,192.168.0.4:24 \
	--nodes 192.168.0.5:25,192.168.0.6:25,192.168.0.7:27 --passwd xxx

create a cluster with custom environment variables:
	sealer run -e DashBoardPort=8443 mydashboard:latest  --masters 192.168.0.2,192.168.0.3,192.168.0.4 \
	--nodes 192.168.0.5,192.168.0.6,192.168.0.7 --passwd xxx


Flags:
      --cluster-name string   set cluster name (default "my-cluster")
      --cmd-args strings      set args for image cmd instruction
  -e, --env strings           set custom environment variables
  -h, --help                  help for run
  -m, --masters string        set Count or IPList to masters
  -n, --nodes string          set Count or IPList to nodes
  -p, --passwd string         set cloud provider or baremetal server password
      --pk string             set baremetal server private key (default "/root/.ssh/id_rsa")
      --pk-passwd string      set baremetal server private key password
      --port uint16           set the sshd service port number for the server (default port: 22) (default 22)
      --provider ALI_CLOUD    set infra provider, example ALI_CLOUD, the local server need ignore this
  -u, --user string           set baremetal server username (default "root")

Global Flags:
      --config string   config file (default is $HOME/.sealer.json)
  -d, --debug           turn on debug mode
      --hide-path       hide the log path
      --hide-time       hide the log time

What you expected to happen:

Successfully initialized the cluster

How to reproduce it (as minimally and precisely as possible):

One initializes the operating system, then executes sealer run xxx

I have the same problem on OpenEuler 22.03.

Error: mount rootfs failed exec init.sh failed failed to execute command(cd /var/lib/sealer/data/my-cluster/rootfs  && chmod +x scripts/* && cd scripts && bash init.sh /var/lib/docker sea.hub 5000) on host(192.168.254.10): error(exit status 1)

It's the same problem with #1454, this issue can be closed.

[allencloud]

It's the same problem with #1454, this issue can be closed.

@iosx I do not think they are the same issue. This issue's problem is init-registry.sh: line 37: docker: command not found

While https://github.com/sealerio/sealer/issues/1454 is the the Ubuntu 22.04 LTS make the sh linked to /bin/dash, rather than /bin/bash.

But they both occurred in the shell srcipts of cd /var/lib/sealer/data/my-cluster/rootfs && chmod +x scripts/* && cd scripts && bash init.sh /var/lib/docker sea.hub 5000

Does the node have a tar command? My problem is caused by the lack of the tar command
