Is there any way to use pushd/popd commands within a Dockerfile? It'd make some install scripts I have a lot easier if it were possible.

Unlike cd command, pushd and popd commands are used to manage a stack of directories. Just enter into a directory and do something you want to do, and "pop" back to the previous directory quickly without having to type the long path name. dirs command is used to show the current directory stack, just like "ls" command.
Both pushd and popd are shell builtin commands. The pushd command is used to save the current directory into a stack and move to a new directory. Furthermore, popd can be used to return back to the previous directory that is on top of the stack.
The pushd command saves the current working directory in memory so it can be returned to at any time, pushd moves to the parent directory. The popd command returns to the path at the top of the directory stack. This directory stack is accessed by the command dirs in Unix or Get-Location -stack in Windows PowerShell.
Run Multiple Commands With Dockerfilethe semicolon (;) operator. the ambersand (&) operator. the AND (&&) operator. the OR (||) operator.
It can be done but your image must have bash and all commands must be in the same RUN directive:
Dockerfile
FROM debian
RUN mkdir -p /test/dir1/dir2
RUN bash -xc "\
pushd /test/dir1; \
pwd; \
pushd dir2; \
pwd; \
popd; \
pwd; \
"
RUN pwd
