Kafka Docker 启动失败

Question

我正在使用 docker swarm 来设置 kafka 队列容器

由于某种原因，自 3 天前以来，kafka 队列无法启动并出现此错误

 dub template "/etc/confluent/docker/${COMPONENT}.properties.template" "/etc/${COMPONENT}/${COMPONENT}.properties"
swarm_stack_kafka-queue.1.xbe7lg7ecc62@xdrdev4    | + dub template /etc/confluent/docker/kafka.properties.template /etc/kafka/kafka.properties
swarm_stack_kafka-queue.1.xbe7lg7ecc62@xdrdev4    | 'ascii' codec can't decode byte 0xe2 in position 8: ordinal not in range(128)
swarm_stack_kafka-queue.1.xbe7lg7ecc62@xdrdev4    | Command [/usr/local/bin/dub template /etc/confluent/docker/kafka.properties.template /etc/kafka/kafka.properties] FAILED !

我运行这个群

奇怪的是，一周前使用的是同一个 compose，我几天前所做的只是删除 swarm 并重新设置... 我最初使用 docker 图像：confluentinc/cp-kafka:4.0.0

但即使将其移动到最新版后仍然会出现同样的问题...

图像来自 confluent 本身，我看不出它为什么会失败或我需要更改任何内容。

有人也遇到过这个问题吗？

你在破折号“-Xmx13G –Xms13G”中发生了一些奇怪的事情

看起来像 copy/paste Unicode 东西。我建议完全放弃该堆设置，因为 Kafka 代理不太可能需要 13G（您可能宁愿将该内存放在页面缓存中）。如果您觉得有必要，请尝试将破折号改成标准的“-”破折号。
