问题描述
目标:要能够运行凤凰,请在ec2实例中混合发行(此机器:https://hub.docker.com/_/amazonlinux/)
问题:运行我的发行版会产生以下错误:
/my_app/erts-11.0.3/bin/beam.smp: /lib64/libtinfo.so.6: no version information available (required by /my_app/erts-11.0.3/bin/beam.smp)
2020-09-08 13:17:33.469328
args: [load_Failed,"Failed to load NIF library /my_app/lib/crypto-4.7/priv/lib/crypto: 'libcrypto.so.1.1: cannot open shared object file: No such file or directory'","OpenSSL might not format: label: be installed on this system.\n"]
"Unable to load crypto library. Failed with error:~n\"~p,~s\"~n~s"
{error_logger,error_msg}
但是在每种情况下(openssl
)我都安装了OpenSSL 1.0.2k-fips 26 Jan 2017
。
设置:
我使用以下命令创建一个新的phoenix项目:
yes | mix phx.new my_app --no-webpack --no-ecto --no-dashboard --no-gettext
cd my_app
并取消注释config :my_app,MyAppWeb.Endpoint,server: true
中的config/prod.secret.exs
行以在运行应用程序时启动服务器。
我创建以下Dockerfile
来构建我的项目:
FROM debian:buster
# Install essential build packages
RUN apt-get update
RUN apt-get install -y wget git locales curl gnupg-agent
# Set locale
RUN sed -i -e 's/# en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/locale.gen && \
dpkg-reconfigure --frontend=noninteractive locales && \
update-locale LANG=en_US.UTF-8
ENV LANG en_US.UTF-8
ENV HOME=/opt/app
workdir /opt/app
# Install erlang and elixir
RUN wget https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb
RUN dpkg -i erlang-solutions_2.0_all.deb
RUN apt-get update
RUN apt-get install -y esl-erlang
RUN apt-get install -y elixir
# Install hex and rebar
RUN mix do local.hex --force,local.rebar --force
# Install phoenix
RUN mix archive.install hex phx_new 1.5.4 --force
copY mix.exs mix.lock ./
copY config config
copY priv priv
copY lib lib
RUN mix deps.get
ENV SECRET_KEY_BASE='secretExampleQrzdplBPdbHHhr2bpELjiGVGVqmjvFl2JEXdkyla8l6+b2CCcvs'
ENV MIX_ENV=prod
RUN mix phx.digest
RUN mix compile
RUN mix release
CMD ["_build/prod/rel/my_app/bin/my_app","start"]
并使用以下图像构建图像:
docker build . -t my_app
我们可以通过以下方法检查一切是否按预期运行:
docker run -p 4000:4000 -i my_app:latest
并访问localhost:4000
。
我从构建的Docker容器复制_build/prod/rel/my_app
目录(因为这就是我要转移到ec2实例的全部内容)。
# list all containers
docker container ls -a
# locate the container with image tag: my_app:latest. It should look like:
# f9c46df97e55 my_app:latest "_build/prod/rel/my_…"
# note the container_id,and copy across the build release
docker cp f9c46df97e55:/opt/app/_build/prod/rel/my_app .
我们创建一个instance.Dockerfile
来运行ec2实例的命令:
FROM amazonlinux:latest
copY my_app my_app
CMD ["my_app/bin/my_app","start"]
并运行它:
docker build . -f instance.Dockerfile -t my_app_instance && docker run -p 4000:4000 -i my_app_instance:latest
[load_Failed,"Failed to 2020-09-08 13:27:49.980715

"Unable to load crypto library. Failed with error:~n\"~p,error_msg}
注意:
我可以使用上面的debian:buster
命令在docker build ... && docker run ...
机器上复制错误,但是要使用此instance.Dockerfile
:
FROM debian:buster
RUN apt-get update
RUN apt-get install -y locales
# Set locale
RUN sed -i -e 's/# en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/locale.gen && \
dpkg-reconfigure --frontend=noninteractive locales && \
update-locale LANG=en_US.UTF-8
ENV LANG en_US.UTF-8
copY my_app my_app
CMD ["my_app/bin/my_app","start"]
并通过将RUN apt-get install -y locales
更改为RUN apt-get install -y locales curl
来纠正错误。
我在yum install curl
机器上尝试过yum install openssl
和amazonlinux:latest
,但是仍然遇到相同的错误。
问题:
我应该在哪里取得进展?这似乎是一个erlang / otp要求问题,但以上内容几乎不是sscce,因此很难提出。
我一直在努力寻找apt-get
curl
软件包安装了什么加密货币或openssl库,从而导致错误得以解决。
任何指向特定论坛寻求帮助或下一步尝试的指针将不胜感激。
预先感谢您的帮助。
解决方法
感谢在@VenkatakumarSrinivasan的CentO上构建它的建议,
我设法使其在具有以下amazonlinux
的{{1}}机器上运行。
构建发行版:
Dockerfile
运行版本:
FROM centos:7
RUN yum update -y
RUN yum clean -y all
RUN echo 'LC_ALL="en_US.UTF-8"' >> /etc/locale.conf
ENV LC_ALL="en_US.UTF-8"
RUN yum install -y epel-release
RUN yum install -y gcc gcc-c++ glibc-devel make ncurses-devel openssl-devel \
autoconf java-1.8.0-openjdk-devel git wget wxBase.x86_64
WORKDIR /opt
RUN wget http://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
RUN rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
RUN yum update -y
RUN yum install -y erlang
WORKDIR /opt/elixir
RUN git clone https://github.com/elixir-lang/elixir.git /opt/elixir
RUN make clean test
ENV PATH=/opt/elixir/bin:${PATH}
RUN mix do local.hex --force,local.rebar --force
RUN mix archive.install hex phx_new 1.5.4 --force
WORKDIR /opt/app
COPY mix.exs mix.lock ./
COPY config config
COPY priv priv
COPY lib lib
RUN mix deps.get
ENV SECRET_KEY_BASE='secretExampleQrzdplBPdbHHhr2bpELjiGVGVqmjvFl2JEXdkyla8l6+b2CCcvs'
ENV MIX_ENV=prod
RUN mix phx.digest
RUN mix compile
RUN mix release
CMD ["_build/prod/rel/my_app/bin/my_app","start"]
我不确定这是否是令人满意的解决方案,但我愿意接受更优雅的解决方案。
