Manage fleet spawns
Fleet Air Traffic Controller (fleet-atc) manages processes that run on your fleet drones. fleet-atc allows you to specify and execute all your fleet spawn commands across all your repos with a single command
[sudo] npm install -g fleet-atc
Installing globally with create a command line tool
Create an empty git repo in a fresh directory. Add a fleet.json file with a default hub.
"remote":"default":"hub": "localhost:7000""secret": "beepboop"
spawn.json In this directory also create a spawn.json
The spawn.json file indicates what process you want to ensure get spawned. Each element in the spawn.json file should contain the command you wish to pass to the fleet-spawn command, as well as the directory of the repo. The directory can either be an absolute path or a relative path to the current directory containing the spawn.json file.
"command": "node grapeServer.js""directory": "../grapes/""command": "node catsServer.js""directory": "../cats/""drone": "drone001"
In the example above, there are 2 repos, grapes.git and cats.git. In each repo you want to issue a different spawn command. fleet-atc will go into each repo specified and execute the given command. Note that you can optionally specify a drone name if the spawned process needs to run on a specific drone. Internally fleet-atc calls
fleet-spawn --drone=drone1 if you specify
To spawn everything in the spawn.json file, execute in the same directory
If any of the elements in spawn.json has already been spawned and thus appears in the output of fleet-ps, fleet-atc will ignore it and move on to the next element
Allow users to specify the max number of times a process can be spawned by including an optional
maxProcesses field in the json element. Currently fleet-atc only allows for 1 process for a given repo directory and command
