Kubernetes记录错误严重性

我将一个python进程部署到k8的pod中。这个过程由一个简单的logger组成：

import sys

import logging
import logging.handlers
from pathlib import Path
import coloredlogs
from app.core.config import settings 
CONFIG_PATH = Path.joinpath(BASE_PATH, '.configrc') 

LOG_FORMAT = f'%(asctime)s.[{settings.APP_NAME}] %(levelname)s %(message)s'
LOG_LEVEL = settings.dict().get('LOG_LEVEL', logging.INFO)
LOGGER = logging.getLogger(__name__)

coloredlogs.install(
    level=LOG_LEVEL,
    fmt=LOG_FORMAT,
    logger=LOGGER) 

LOGGER.info("INFO Creating main objects...")

然而，当我检查k8中的日志时，它总是抱怨那些日志是错误的：

ERROR 2023-06-01T13:54:37.742688222Z [resource.labels.containerName: myapp] 2023-06-01 15:54:37.[myapp] INFO Creating main objects...

{
insertId: "8xj2l2hwts2f45gt"
labels: {4}
logName: "projects/proj-iot-poc/logs/stderr"
receiveTimestamp: "2023-06-01T13:54:38.596712564Z"
resource: {2}
severity: "ERROR"
textPayload: "2023-06-01 15:54:37.[myapp] INFO Creating main objects..."
timestamp: "2023-06-01T13:54:37.742688222Z"
}

不值得说的是，我刚刚使用了LOGGER.info("Creating main objects...")，我希望日志只是一个信息不和错误...

也许这与以下内容有关：GCP and Python Logging

kubernetes

按热度按时间

在抓取网页后，我明白了GCP不支持Python的日志记录。最后，我写了一个自定义logger：

"""
General colorized Logger compatible with GCP
"""
import os
import sys
import datetime
import pprint

from typing import TextIO

class CustomLogger:
    BLACK = '\033[0;30m'
    RED = '\033[0;31m'
    GREEN = '\033[0;32m'
    BROWN = '\033[0;33m'
    BLUE = '\033[0;34m'
    PURPLE = '\033[0;35m'
    CYAN = '\033[0;36m'
    GREY = '\033[0;37m'

    DARK_GREY = '\033[1;30m'
    LIGHT_RED = '\033[1;31m'
    BOLD_RED = "\x1b[31;1m"
    LIGHT_GREEN = '\033[1;32m'
    YELLOW = '\033[1;33m'
    LIGHT_BLUE = '\033[1;34m'
    LIGHT_PURPLE = '\033[1;35m'
    LIGHT_CYAN = '\033[1;36m'
    WHITE = '\033[1;37m'
    RESET = "\033[0m"
    pippo = "1"

    def __init__(self, fmt: str = ""):
        self.fmt = f"%(asctime).[{os.getenv('APP_NAME')] %(levelname) %(message)"
        self.terminal_type = os.getenv('TERM') or ""

    def debug(self, message: str = ""):
        out = self.__format(message)
        self.sprint(self.DARK_GREY, message=out)

    def warning(self, message: str = ""):
        out = self.__format(message)
        self.sprint(self.CYAN, message=out)

    def info(self, message: str = ""):
        out = self.__format(message, 'INFO')
        self.sprint(self.GREEN, message=out)

    def critical(self, message: str = ""):
        out = self.__format(message, 'CRITICAL')
        self.sprint(self.BOLD_RED, message=out, file=sys.stderr)

    def exception(self, message: str = ""):
        out = self.__format(message, 'CRITICAL')
        self.sprint(self.LIGHT_RED, message=out, file=sys.stderr)

    def error(self, message: str = ""):
        out = self.__format(message, 'ERROR')
        self.sprint(self.RED, message=out, file=sys.stderr)

    def __format(self, message, level: str = ""):
        now = datetime.datetime.now().strftime('%Y-%m-%dT%H:%M')
        message = pprint.pformat(message)
        return self.fmt.replace("%(message)", message).\
            replace("%(asctime)", now).\
            replace("%(levelname)", level)

    def sprint(self, color, message, file: TextIO = sys.stdout):
        if 'xterm' in self.terminal_type:
            print(color + message + self.RESET)
        else:
            print(message)

LOGGER = CustomLogger()

省略了一些代码优化。
