当docker容器中创建时,在本地无法访问软链接
我有一个使用Dockerfile从自定义WF图像运行的野生蝇容器。在这里,我已将自定义的独立full.xml文件添加到wf的配置文件夹(/opt/jboss/jboss/wildfly/standalone/configuration
),并相应地构建图像。 在Docker运行期间,我没有安装配置文件夹,因为我们无法进行反向安装(容器到主机),但是我需要andalone-full-app.xml
要安装到本地。
因此,我尝试了软链接以创建内部容器,并将其安装到相应的目录,该目录在Docker Run命令期间安装在本地。
docker exec <wf_container> ln -s /opt/jboss/wildfly/standalone/configuration/standalone-full-app.xml /opt/jboss/wildfly/standalone/appconfig/
该目录已安装到我的本地主机-v/home/user/docker/docker/app/config/:/opt/jboss/jboss/wildfly/standalone/appconfig/
我能够读取/编写软链接内部容器(/opt/jboss/wildfly/standalone/aspconfig/standalone-full-app.xml
),它在实际文件中反射。
但是我无法在本地访问的同一文件,它说找不到这样的文件或目录。
有人可以帮助我实现我的独立 - full-app.xml
在本地访问的文件吗?

I have a wildfly container that is running from the custom WF Image using Dockerfile. Here I have added the custom standalone-full.xml file to the config folder(/opt/jboss/wildfly/standalone/configuration
) of wf and building the image accordingly.
And during docker run I am not mounting the config folder as we can't able to do reverse mounting(container to host) but I need that standalone-full-app.xml
file to be mounted to local.
So I tried soft link to create inside container and mount it to the respective directory, which is mounted to local during docker run command.
docker exec <wf_container> ln -s /opt/jboss/wildfly/standalone/configuration/standalone-full-app.xml /opt/jboss/wildfly/standalone/appconfig/
This directory is mounted to my local host -v /home/user/docker/app/config/:/opt/jboss/wildfly/standalone/appconfig/
I can able to read/write the soft link inside container (/opt/jboss/wildfly/standalone/appconfig/standalone-full-app.xml
) and it is reflecting in actual file.
but the same file I can't able to access in my local, it says no such file or directory found.
can someone please help me to achieve accessing my standalone-full-app.xml
file accessible in local?

您为软链接/符号链接使用了绝对路径名。但是,如果安装点发生变化,则操作系统将不再遵循该路径。
如果Symlink的源和目标都位于同一文件系统中,请尝试创建一个具有相对路径的符号链接:
在这里您有机会在容器内外成功解决了Symlink。
You used absolute path names for your softlink/symlink. But if the mount point changes, the OS can no longer follow that path.
If both source and destination for the symlink are in the same filesystem, try to create a symlink with relative path:
Here you have a chance the symlink resolves successfully inside and outside the container.
