appmesh 2.1.18

Client SDK for App Mesh

Advanced Application Management Platform

App Mesh is a secure platform for executing and managing user-defined process behaviors as managed services, providing control and integration via CLI and RESTful APIs.

App Mesh = systemd + scheduler + remote exec + API

1. Application Management

Manages user-defined processes in a way similar to systemd services or Docker-managed processes, while providing more advanced capabilities for control, security, and integration.

# List registered applications
$ appc ls
ID  NAME    OWNER  STATUS    HEALTH  PID  USER  MEMORY    %CPU  RETURN  AGE  DURATION  STARTS  COMMAND
1   pyexec  mesh   disabled  -       -    -     -         -     -       37s  -         0       "python3 ../../bin/py_exec.py"
2   ping    mesh   enabled   OK      747  root  5.9 MiB   0     -       37s  37s       1       "ping cloudflare.com"
3   pytask  mesh   enabled   OK      748  root  29.7 MiB  0     -       37s  37s       1       "python3 ../../bin/py_task.py"
# Add app
$ appc add -a myapp -c "ping www.baidu.com"
# View app
$ appc ls -a myapp -o
PING www.baidu.com (183.2.172.17) 56(84) bytes of data.

64 bytes from 183.2.172.17 (183.2.172.17): icmp_seq=3 ttl=52 time=35.3 ms
# appc -h for more usage

Supports not only long-running services, but also scheduled and policy-driven executions, with remote control and execution status tracking.

2. Sending Tasks to a Running Application

Interact with a running application by sending tasks or data to it and receiving responses through the SDK.

from appmesh import AppMeshClient
client = AppMeshClient()
client.login("USER-NAME", "USER-PWD")

result_from_server = "0"
for i in range(10):
    task_data = f"print({result_from_server} + {i}, end='')"
    result_from_server = client.run_task(app_name="pytask", data=task_data)
    print(result_from_server)
