Are you trying to resolve docker error while loading shared libraries?
This guide is for you.
Generally, Docker error while loading shared libraries happens in the process of building a docker image.
Here at Ibmi Media, as part of our Server Management Services, we regularly help our Customers to fix Docker related errors.
In this context, we shall look into how to resolve this Docker error.
How to get rid of the error 'Docker error while loading shared libraries' ?
To fix this error, apply the tip given below.
One of our customers came across this error message while building a docker image.
He was using the COPY command to copy a local file from the host into my container.
After building the image, he ran an interactive shell to test the file.
Also, he placed a "software" directory under the Dockerfile directory which has XYZ executable. But after entering the container built by the image and running the executable, he ran into the below error message:
root@server:/bin# ./xyz ./xyz: error while loading shared libraries: libxyz.so.3: cannot open shared object file: No such file or directory
One checking, we found that here, the error tells that the customer has copied over the executable, but it has dependencies on various libraries (including libxyz.so.3) that aren't in the container.
So, we suggested the below to resolve this error message.
i. Add the dependencies to the container.
ii. By running ldd tool on executable, we can find which dependencies it requires.
iii. Either can copy the libraries directly into the container as done with the executable.
iv. Or find which package the dependencies are from and install with apt-get.
v . recompile the executable so that it is statically linked.
