Hallo zusammen,

ich habe eine docker-compose.yml und möchte diese editieren, was mir 
nicht gelingt.

#!/usr/bin/python3
  2
  3 import subprocess
  4 import shutil
  5 import os
  6 import docker
  7 #client = docker.DockerClient(base_url="unix://var/run/docker.sock", 
version='auto')
  8 client = docker.from_env()
  9 import sys
10 import yaml
11print(sys.version)
12
1
21
22
23 with open('docker-compose.yml', "r") as f:

24     # The FullLoader parameter handles the conversion from YAML
25     # scalar values to Python the dictionary format26     # 
docker_compose = yaml.load(file, Loader=yaml.FullLoader)

27     docker_compose  = yaml.full_load(f)

28 #    docker_compose  = yaml.load(f, Loader=yaml.FullLoader)
29 #    docker_compose['MYSQL_ROOT_PASSWORD'] = "test"
30 
#docker_compose["services"]["db"]["environment"]['MYSQL_ROOT_PASSWORD'] 
= docker_compose.update("{{{pass}}}", "passing")
31
32     #docker_compose.update("{{{pass}}}", "Passing")
33
34    # txt = "pass"
35    # x = txt.replace("pass", "apples")
36     docker_compose["services"]["db"]["environment"] = 
docker_compose.update("pass", "apples")
37
38 #    print(docker_compose)
39    # docker_compose = docker_compose.replace("{{{pass}}}", 
"passingpass")
40
41
42 with open('docker-compose.yml', "w") as f:
43     yaml.dump(docker_compose, f)

in der docker-compose habe ich bei MYSQL_ROOT_PASSWORD=pass eingetragen, 
weil ich dachte, wenn ich da was einfaches stehen habe, kann ich es 
ersetzen.

Das funktioniert so leider nicht. Jetzt wird bis "environment" in der 
yaml alles weggeschnitten.


Wie kann ich eine docker-compose.yml mit  python editieren?

Kann jemand helfen?


Danke!

Gruß

Stefan
