Docker容器中node-oracledb的问题
Docker容器中node-oracledb的问题
提问于 2020-06-16 12:14:24
我有一个通过TypeORM连接到Oracle数据库的Nest.js应用程序，我正在尝试使用Docker将我的应用程序容器化。所以这里的问题是，当应用程序没有被容器化时，它工作得很好，但当我这样做时，我得到了以下错误。
[Nest] 19 - 06/16/2020, 4:00:52 AM [TypeOrmModule] Unable to connect to the database. Retrying (4)... +3003ms
Error: DPI-1047: Cannot locate a 64-bit Oracle Client library: "libclntsh.so: cannot open shared object file: No such file or directory". See https://oracle.github.io/odpi/doc/installation.html#linux for help
Node-oracledb installation instructions: https://oracle.github.io/node-oracledb/INSTALL.html
You must have 64-bit Oracle client libraries in LD_LIBRARY_PATH, or configured with ldconfig.
If you do not have Oracle Database on this computer, then install the Instant Client Basic or Basic Light package from

at OracleDb.createPool (/app/node_modules/oracledb/lib/oracledb.js:202:8)
at OracleDb.createPool (/app/node_modules/oracledb/lib/util.js:185:19)我确保在Dockerfile中添加Oracle瘦客户机所需的依赖项，如下所示
FROM oraclelinux:7-slim
RUN yum -y install oracle-release-el7 oracle-nodejs-release-el7 && \
yum-config-manager --disable ol7_developer_EPEL --enable ol7_oracle_instantclient && \
yum -y install oracle-instantclient19.5-basiclite && \
rm -rf /var/cache/yum
FROM node:10
WORKDIR /app
COPY ./package.json ./我不确定要在这里添加什么才能使其正常工作。我从这里的https://oracle.github.io/node-oracledb/INSTALL.html#docker获得了一些关于如何为oracle客户端添加内容的说明

看起来您正在尝试使用多阶段构建。我在我的博客posst Docker for Oracle Database Applications in Node.js and Python的"Node.js Dockerfile示例3“中讨论了这一点。
您可以尝试如下所示：
FROM oraclelinux:7-slim as builder
ARG release=19
ARG update=5
RUN yum -y install oracle-release-el7 &&
oracle-instantclient${release}.${update}-basiclite
RUN rm -rf /usr/lib/oracle/${release}.${update}/client64/bin
WORKDIR /usr/lib/oracle/${release}.${update}/client64/lib/
RUN rm -rf *jdbc* *occi* *mysql* *jar
# Get a new image
FROM node:12-buster-slim
# Copy the Instant Client libraries, licenses and config file from the previous image
COPY --from=builder /usr/lib/oracle /usr/lib/oracle
COPY --from=builder /usr/share/oracle /usr/share/oracle
COPY --from=builder /etc/ld.so.conf.d/oracle-instantclient.conf /etc/ld.so.conf.d/oracle-instantclient.conf
RUN apt-get update && apt-get -y upgrade && apt-get -y dist-upgrade && apt-get install -y libaio1 && \
apt-get -y autoremove && apt-get -y clean && \
ldconfig总体而言，这可能不值得这么复杂。看看博客文章中的另一个例子。或者使用Oracle的Dockerfile文件：https://github.com/oracle/docker-images/tree/master/OracleLinuxDevelopers/oraclelinux7/nodejs/12-oracledb
