==== lxcreate ====
<pre>
[root@smartos ~]# /zones/lxcreate
Usage: ./lxcreate <alias> <ip> <env> [mem=64] [swap=256] [image_uuid=0b7d45d9-be8c-439f-9a24-bd6223199c2b]
NOTE: alias is used for docker image, by default alias:latest is used
IE: docker run alias:latest
ex: ./lxcreate mediawiki 192.168.3.123/24
ex: ./lxcreate ghost 192.168.3.123/24 NODE_ENV=development
ex: ./lxcreate ghost 192.168.3.123/24 NODE_ENV=development 128 256</pre>

==== mediawiki ====

==== ghost ====
sometimes you need to set environment variables (https://hub.docker.com/_/ghost)
<pre>
$ podman run -d --name some-ghost -e NODE_ENV=development ghost
</pre>
<pre>
[root@smartos ~]# vm-create ghost 192.168.3.123/24 NODE_ENV=development
Successfully created VM 7ceaeea2-7bc4-4e89-ab3f-da516982548b
</pre>
sometimes you need to delete/edit the entrypoint
<syntaxhighlight copy>

# not sure why, but this was needed

vmadm reboot $uuid

<pre>
[root@smartos ~]# alias=ghost
