ssh_cmds

Type: array

Value: ["<cmd-str>", "<cmd-str>", ... , "<cmd-str>"]

Attribute: If key is set as ssh, then value should be ssh_cmds only

Parent: None

List of commands executed by ssh. <cmd-str> is the standard linux command.

If you need to execute complicated commands including conditional-branch or loop-body, please write a standalone script and add execute it by <cmd-str>:

[
    {
        "key": "scp",
        "value":
        [
            ......
            { "local": "upgrade.sh", "remote": "/data/tmp/" }
            ......
        ]
    },
    {
        "key": "ssh",
        "value":
        [
            ......
            "sh upgrader.sh"
            ......
        ]
    }
    ......
]

Special tag: @index_place_holder

If <cmd-str> is configured with @index_place_holder, deploygen will replace the tag with the sequence number in order of machines stored in host_file.

For instance, configure deploy.json like this:

[
    {
        "key": "scp",
        "value":
        [
            { "local": "zookeeper-3.4.8.tar.gz", "remote": "/data/" }
        ]
    },
    {
        "key": "ssh",
        "value":
        [
            "cd /data",
            "test -d zookeeper-3.4.8 && mv zookeeper-3.4.8 zookeeper-3.4.8-old",
            "tar -zxf zookeeper-3.4.8.tar.gz -C ."
        ]
    },
    {
        "key": "scp",
        "value":
        [
            { "local": "zoo.cfg", "remote": "/data/zookeeper-3.4.8/conf/" }
        ]
    },
    {
        "key": "ssh",
        "value":
        [
            "cd /data/zookeeper-3.4.8",
            "mkdir -p data",
            "cd data/",
            "echo \"@index_place_holder\" > myid",
            "cd ../../",
            "rm -f zookeeper-3.4.8.tar.gz"
        ]
    }
]

Edit host.txt as below:

192.168.1.101
192.168.1.102
192.168.1.103

Run command:

python deploygen.py jobs deploy.json host.txt > deploy.sh

The output script:

#!/bin/sh

As you see, @index_place_holder is replaced by the sequence number in order.
