在码头图像中添加.jar文件

Question

嗨，我正在使用，并在其中添加一个.jar文件，并创建docker映像。

这是我一直试图添加到我的码头映像中的.jar文件。

ARG JAR_FILE=target/jts-core-1.15.0-javadoc.jar
ADD  ${JAR_FILE} /server/solr-webapp/webapp/WEB-INF/lib/testing.jar

下面是我一直用来创建的docker文件，我还添加了一个卷来保存数据。当我构建码头映像时，它会将.jar文件添加到指定的路径中。但是，它删除默认solr dockerfile中创建的所有其他jar文件。

我可以在dockerfile中添加什么，这样它就可以添加新的.jar文件并包含已经创建的.jar文件。

Answer 1

您可以在构建jar文件时将其复制到docker映像中。

COPY <PATH TO YOUR JAR ON MACHINE> <PATH TO THE JAR YOU WANT IN THE DOCKER IMAGE>

这将将文件从主机复制到docker映像的目录中。

COPY target/jts-core-1.15.0-javadoc.jar target/jts-core-1.15.0-javadoc.jar

上面的示例将显示在当前路径的COPY目录中的jts-core-1.15.0-javadoc.jar文件转到停靠图像的target目录中。

发布ARGS和ADD的命令应该按照预期工作。

COPY target/jts-core-1.15.0-javadoc.jar target/jts-core-1.15.0-javadoc.jar
ARG JAR_FILE=target/jts-core-1.15.0-javadoc.jar
ADD  ${JAR_FILE} /server/solr-webapp/webapp/WEB-INF/lib/testing.jar

Answer 2

更新

在玩了一会儿码头文件之后，我发现了这个问题。

我也会更新上面的Dockerfile。

我不需要在我的停靠文件中创建卷，因为它是不需要的。

我添加了下面的行，它复制了我的.jar文件，而没有删除以前的文件

COPY <Your jar file>/opt/solr-$SOLR_VERSION/<Input path here where to copy jar file"
