APM - Golang应用程序的一个进程管理器拥有一个HTTP API
# APM - Aguia Process Manager APM is a lightweight process manager written in Golang for Golang applications. It helps you keep your applications alive forever, reload and start them from the source code.
Starting an application is easy:
$ ./apm bin app-name --source="github.com/topfreegames/apm"
This will basically compile your project source code and start it as a daemon in the background. The application will have already be downloaded into GOPATH issuing something like
go get github.com/topfreegames/apm
You will probably be able to run anything in any directory, as long as it is under GOPATH
Install APM
$ go get github.com/topfreegames/apm
Start APM
In order to properly use APM, you always need to start a server. This will be changed in the next version, but in the meantime you need to run the command bellow to start using APM.
$ apm serve
If no config file is provided, it will default to a folder '.apmenv' where apm is first started.
Stop APM
$ apm serve-stop
Starting a new application
If it's the first time you are starting a new golang application, you need to tell APM to first build its binary. Then you need to first run:
$ apm bin app-name --source="github.com/yourproject/project"
This will automatically compile, start and daemonize your application. If you need to later on, stop, restart or delete your app from APM, you can just run normal commands using the app-name you specified. Example:
$ apm stop app-name$ apm restart app-name$ apm delete app-name
Main features
Commands overview
$ apm serve --config-file="config/file/path.toml"$ apm serve-stop --config-file="config/file/path.toml"$ apm bin app-name --source="github.com/topfreegames/apm" # Compile, start, daemonize and auto restart application.$ apm start app-name # Start, daemonize and auto restart application.$ apm restart app-name # Restart a previously saved process$ apm stop app-name # Stop application.$ apm delete app-name # Delete application forever.$ apm save # Save current process list$ apm resurrect # Restore previously saved processes$ apm status # Display status for each app.
Managing process via HTTP
You can also use all of the above commands via HTTP requests. Just set the flag --dns together with ./apm serve and then you can use a remote client to start, stop, delete and query status for each app.
