在alpine docker上运行的perl-cassandra客户端最好是哪一个&如何安装和使用它?
请提供docker文件或至少docker命令和连接到cassandra的poc脚本。
下面是使用dbd::cassandra库的最新尝试docker文件实际上成功完成并部署了get:
FROM alpine:3.10.3
## alpine curl and wget aren't fully compatible, so we install them
## here. gnupg is needed for Module::Signature.
RUN apk update && apk upgrade
RUN apk add --no-cache curl tar make gcc build-base wget gnupg ca-certificates g++ git gd-dev
RUN apk add --no-cache zlib zlib-dev
RUN apk add --no-cache perl perl-dev
RUN apk add --no-cache perl-app-cpanminus
RUN cpanm App::cpm
WORKDIR /usr
RUN cpm install Try::Tiny
RUN cpm install YAML
RUN cpm install JSON
RUN cpm install JSON::MaybeXS
RUN cpm install HTTP::Request
RUN cpm install HTTP::Response
RUN cpm install HTTP::Daemon
RUN cpm install GD::Simple
RUN cpm install GD::Graph
RUN cpm install Data::HexDump::Range
RUN cpm install Proc::Daemon
RUN cpm install Test::Block
RUN cpm install Text::Colorizer
RUN cpm install Gzip::Faster
ENV PERL5LIB=/usr/local/lib/perl5
ENV PATH=/usr/local/bin:$PATH
RUN apk add --no-cache musl-obstack-dev --repository=http://dl-cdn.alpinelinux.org/alpine/edge/main
RUN cpm install Proc::ProcessTable
RUN cpm install Kafka::Connection
RUN apk add --update openssl && \
rm -rf /var/cache/apk/*
# RUN cpm install DBI
RUN cpm install DBD::Cassandra
COPY run.sh /run.sh
RUN chmod +x "/run.sh"
RUN mkdir -p /code_path
WORKDIR /code_path
CMD ["/run.sh"]
以下是脚本:
use Data::Dumper;
use DBD::Cassandra;
use DBI;
say("Mama");
my $user = undef;
my $password = undef;
my $host = 'cassandra.cassandra.svc.cluster.local';
my $keyspace = 'grids';
my $table = 'electricity_grid';
my $dbh = DBI->connect("dbi:Cassandra:host=$host;keyspace=$keyspace", $user, $password, { RaiseError => 1 });
my $rows = $dbh->selectall_arrayref("SELECT * FROM $table");
for my $row (@$rows) {
# Do something with your row
say($row);
}
但代码示例的工作方式与未安装库的情况不同:
bash-5.0# ./demoCassandra.pl
Can't locate DBD/Cassandra.pm in @INC (you may need to install the
DBD::Cassandra module) (@INC contains: /usr/local/lib/perl5/5.28.2/x86_64-linux-thread-multi /usr/local/lib/perl5/5.28.2 /usr/local/lib/perl5/x86_64-linux-thread-multi /usr/local/lib/perl5 /usr/local/lib/perl5/site_perl /usr/local/share/perl5/site_perl /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5/core_perl /usr/share/perl5/core_perl) at ./demoCassandra.pl line 7.
BEGIN failed--compilation aborted at ./demoCassandra.pl line 7.
这是一个古老的尝试:我把它放在这里是因为下面@valiano的答案的相关性。
我找到的最新库是:dbd::cassandra,因此我尝试在alpine docker上安装perl dbd::cassandra,但失败了:
cpm install DBD::Cassandra
读取日志后,我成功安装了
cpm install IO::Socket::INET6
安装失败
cpm install OpenSSL
以下是基本文件:
FROM alpine:3.10.3
## alpine curl and wget aren't fully compatible, so we install them
## here. gnupg is needed for Module::Signature.
RUN apk update && apk upgrade
RUN apk add --no-cache curl tar make gcc build-base wget gnupg ca-certificates g++ git gd-dev
RUN apk add --no-cache zlib zlib-dev
RUN apk add --no-cache perl perl-dev
RUN curl -L <this was cencored by stack overflow>cpanm > /bin/cpanm && chmod +x /bin/cpanm
RUN cpanm App::cpm
WORKDIR /usr
RUN cpm install Try::Tiny
RUN cpm install YAML
RUN cpm install JSON
RUN cpm install JSON::MaybeXS
RUN cpm install HTTP::Request
RUN cpm install HTTP::Response
RUN cpm install HTTP::Daemon
RUN cpm install GD::Simple
RUN cpm install GD::Graph
RUN cpm install Data::HexDump::Range
RUN cpm install Proc::Daemon
RUN cpm install Test::Block
RUN cpm install Text::Colorizer

ENV PERL5LIB=/usr/local/lib/perl5

RUN cpm install Proc::ProcessTable
RUN cpm install Kafka::Connection
COPY run.sh /run.sh
RUN chmod +x "/run.sh"
RUN mkdir -p /code_path
WORKDIR /code_path
CMD ["/run.sh"]
输出失败文件表明io::socket::inet6 openssl丢失:
bash-5.0# tail /root/.cpanm/work/1582818617.3526/build.log

通过以下调整,我成功地构建了附加的dockerfile:
为了
/bin/cpanm
,使用alpine的本机包perl app cpanminus:RUN apk add --no-cache perl-app-cpanminus
(而不是手动下载cpanm
二进制-这是一个特殊的定制版本吗?)musl obstack dev已从
edge/testing
到edge/main
存储库:RUN apk add --no-cache musl-obstack-dev --repository=http://dl-cdn.alpinelinux.org/alpine/edge/main

经过两天的摆弄,我来到了这个码头:
此脚本在docker中工作(在kubernetes桌面上):
