Question

我正在尝试启动docker容器；容器以状态代码1退出，表示错误。看起来像是内存错误；但是，请求的内存（〜900Mo）小于可用的内存（〜8Go）。 docker logs产生以下错误：

OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000ca660000, 899284992, 0) failed; error='Not enough space' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 899284992 bytes for committing reserved memory.
# An error report file with more information is saved as:
# logs/hs_err_pid1.log

我的docker info is as such：

你知道我该怎么解决吗？

有关信息，我的Dockerfile就这样，构建图像时没有问题。

FROM python:3.6-alpine

RUN adduser -D microblog

WORKDIR /home/microblog

COPY requirements.txt requirements.txt
RUN python -m venv venv
RUN apk add --no-cache --virtual .pynacl_deps build-base python3-dev libffi-dev
RUN venv/bin/pip install -r requirements.txt
RUN venv/bin/pip install gunicorn
RUN venv/bin/pip install gunicorn 'pymysql<0.9'

COPY app app
COPY migrations migrations
COPY microblog.py config.py boot.sh ./
RUN chmod +x boot.sh

ENV FLASK_APP microblog.py

RUN chown -R microblog:microblog ./
USER microblog

EXPOSE 5000
ENTRYPOINT ["./boot.sh"]

在AWS上运行docker时遇到相同的问题。但是您可以通过将以下参数传递给docker来增加Java可用于运行应用程序的内存来解决此问题： -e ES_JAVA_OPTS =“-Xms108m -Xmx108m”

希望这会有所帮助！ l！

Docker：没有足够的内存让Java Runtime Environment继续运行
