Docker - library initialization failed - unable to allocate file descriptor table - out of memory

Question

I have been try to run Zookeeper and Kafka on Docker container. I got a lot of errors [error occurred during error reporting , id 0xb] and [Too many errors, abort] in my terminal. And then library initialization failed - unable to allocate file descriptor table - out of memory.

I use the following docker-compose.yml file

version: "3.8"
services:
  zookeeper:
    image: confluentinc/cp-zookeeper:5.5.4
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181
      ZOOKEEPER_TICK_TIME: 2000
  kafka:
    image: confluentinc/cp-kafka:5.5.4
    # If you want to expose these ports outside your dev PC,
    # remove the "127.0.0.1:" prefix
    ports:
      - 127.0.0.1:9092:9092
    environment:
      KAFKA_BROKER_ID: 1
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:29092,PLAINTEXT_HOST://localhost:9092
      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT
      KAFKA_INTER_BROKER_LISTENER_NAME: PLAINTEXT
      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1

Answer 1

我通过覆盖ExecStartdocker.service 中的命令参数解决了这个问题

sudo systemctl edit docker

然后输入

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd --default-ulimit nofile=65536:65536 -H fd://

保存并运行sudo systemctl daemon-reload并sudo systemctl restart docker.

Answer 2

尝试将ulimits配置添加到zookeeper中

---
version: '3'
services:
  zookeeper:
    image: wurstmeister/zookeeper
    ulimits:
      nofile:
        soft: 65536
        hard: 65536
    ports:
      - "2181:2181"
