        # Introduction
        
        Mordor is a tool helps you to deploy your python project.
        
        # Config
        
        ## Config directory
        
        * If you specify `-c` option, mordor uses the config directory you specified after `-c` option
        * If you have environment variable `MORDOR_CONFIG_DIR` set, mordor uses it as config directory
        * Otherwise, mordor uses `~/.mordor` as config directory
        
        
        
        mordor reads config from `~/.mordor/config.json` or if you specify `-c` option to override it, for example if you have `-c /home/stonezhong/testmordor/.mordor` then mordor will read config from `/home/stonezhong/testmordor/.mordor/config.json`
        
        ## Config structure
        Here is an example:
        ```json
        {
            "hosts": {
                "mordortest": {
                    "ssh_host"  : "mordortest",
                    "env_home"  : "/root/mordor",
                    "virtualenv": "/usr/bin/virtualenv",
                    "python3"   : "/usr/bin/python3"
                }
            },
            "deployments": {
                "sample_beta": {
                    "name"        : "sample",
                    "stage"       : "beta",
                    "home_dir"    : "/home/stonezhong/DATA_DISK/projects/mordor/sample",
                    "deploy_to"   : [ "mordortest" ],
                    "use_python3" : true,
                    "config"      : {
                        "foo.json": "copy"
                    }
                }
            }
        }
        ```
        
        * In `hosts` section, you need to list all your target machine which you want to deploy to.
            * You need to make sure you can ssh to each machine without entering password, you can config your `~/.ssh/config` if needed
            * If your target machine support python3, you need to specify python3 location
            * `env_home` is the root path for mordor, normally you want to point it to a large disk, for example `/mnt/mordor`
            * `ssh_host` is the name of the host when you do ssh, normally it should match what you have in your `~/.ssh/config` file
        * In `deployments` section, you list all the deployments you want to deploy
            * `name` is the name of the application, if missing, then the deployment name becomes the application name
            * `stage` is the name of the stage, usually it is something like `beta`, `prod`, etc, but it can be anything
                * The same application can have as many stages as it can, but each target can only deploy one stage. For example, you cannot deploy both beta and prod stage of the same app to the same target
            * `deploy_to` is a list of the target's name
            * `use_python3`: set to true if your app need python3
            * the `config` section list all the config file you need to deploy to the target
            * when looking for config file xyz, mordor lookup the config in `<base_config_dir>/configs/<app_name>/<stage>/xyz`, then then fallbacks to `<base_config_dir>/configs/<app_name>/xyz`
                * <base_config_dir> is `~/.mordor` by default, or you can use `-c` option to change it.
            * `stage`: the stage of this deployment, if missing, then stage is ""
        
        
        # Sample commands
        ## Init target host
        <details>
        <summary>Initialize target host</summary>
        
        ```bash
        # initialize mordor on target host mordortest, using config file from /home/stonezhong/testmordor/.mordor
        mordor -c /home/stonezhong/testmordor/.mordor -a init-host -o mordortest
        ```
        </details>

        <details>
        <summary>Stage application to target</summary>
        
        ```bash
        # stage application sample to beta stage
        # the application will be copied to the target machine
        # configuration will be copied to the target machine
        # python virtual environment will be created on target machine
        mordor -c /home/stonezhong/testmordor/.mordor -a stage -p sample -s beta
        ```
        </details>

        <details>
        <summary>Run a command on target</summary>
        
        ```bash
        # run command
        # application is "sample", stage is "beta", command is "foo" with option "xyz abc"
        mordor -c /home/stonezhong/testmordor/.mordor -a run -p sample -s beta -cmd foo -co "xyz abc"
        ```

        # Application Structure
        
        You can look at the [Sample](https://github.com/stonezhong/mordor/tree/master/sample)
        
        * You need to have a manifest.json file, you normally want to bump the version if you make changes to your application.
        * You need to have a requirements.txt in your application root which tells list of packages you need to install
        * Optional, if you want to support running remote command, you need to have a `dispatch.py`. When you run `mordor -a run ...`, this python code will be invoked to handle the command
        
        # Command line options
        ```
        mordor \
          -c <mordor_config_base> \
          -a <action> \
          -o <target_name> \
          -p <app_name> \
          -s <stage> \
          -cmd <your command here> \
          -co <your command arguments here>
        
        # -c, if missing , mordor looks for config in ~/.mordor
        # -a, action, could be `init-host`, `stage` or `run`
        # -o, specify the the target machine.
        #     for init-host, you must specify this
        #     for stage or run, if missing, then the scope is all the target for the stage
        # -p, the application name
        # -s, the stage name, if missing, the stage name is empty string
        # -cmd, the command you want to run when your action is "run"
        # -co, the command arguments when your action is "run"
        ```
        
        # Target host mordor file structure
        ```
