What I have so far:
cat Dockerfile
FROM centos:7 AS env
RUN yum update -y
RUN yum install -y centos-release-scl
RUN yum install -y devtoolset-9
RUN echo "source /opt/rh/devtoolset-9/enable" >> /etc/bashrc
SHELL ["/bin/bash", "--login", "-c"]
RUN gcc --version
So you must:
Add the source stuff in a bashrc
note: On Centos it's/etc/bashrcwhile on ubuntu it's/etc/bash.bashrcUpdate the docker default shell to be bash AND to "load" the bashrc using
--login
Output
docker build .

What won't work
Test 1
RUN scl enable devtoolset-9 bash
RUN gcc --version | head -1
each RUN is a new shell so the sub-bash is lost on the second line.
Test 2
RUN source /opt/rh/devtoolset-9/enable && gcc --version | head -1
RUN gcc --version | head -1
Here again the source is only for the first RUN shell command but will be lost...
Test 3
This may work but with potential unexpected behaviour
ENV PATH=/opt/rh/devtoolset-9/root/bin:$PATH
RUN gcc --version | head -1
here we only "fix" the PATH variable but if you look at the /opt/rh/devtoolset-9/enable script there is so more to do than only updating the PATH...

You may give it a try using the below steps if that may help: Download the latest package from http://ftp.gnu.org/gnu/gcc/gcc-9.2.0/
wget http://ftp.gnu.org/gnu/gcc/gcc-9.2.0/gcc-9.2.0.tar.gz
Extract the files using the steps below:
tar -xzvf gcc-9.20.tar.gz
cd gcc-9.2.0
Build a configuration using the below,
./configure
Compile the installation using make and then make install.
make
make install
yum install centos-release-scl-rh

While trying to install gcc, I came upon an error. I suspect something wrong with the repo configs, as I can download the rpms it complains about, and manually install them alongside gcc without issue.
EDIT: Nevermind, known bug... but I'll leave this here for anyone who comes looking.

Is this ok [y/N]:Update:
Often people want the most recent version of gcc, and devtoolset is being kept up-to-date, so maybe you want devtoolset-N where N={4,5,6,7...}, check yum for the latest available on your system). Updated the cmds below for N=7.
There is a package for gcc-7.2.1 for devtoolset-7 as an example. First you need to enable the Software Collections, then it's available in devtoolset-7:
sudo yum install centos-release-scl
sudo yum install devtoolset-7-gcc*
scl enable devtoolset-7 bash
which gcc
gcc --version
Update: Installing latest version of gcc 9: (gcc 9.3.0) - released March 12, 2020:
Same method can be applied to gcc 10 (gcc 10.1.0) - released May 7, 2020
Download file: gcc-9.3.0.tar.gz or gcc-10.1.0.tar.gz
Compile and install:
//required libraries: (some may already have been installed)
dnf install libmpc-devel mpfr-devel gmp-devel
//if dnf install libmpc-devel is not working try:
dnf --enablerepo=PowerTools install libmpc-devel
//install zlib
dnf install zlib-devel*
./configure --with-system-zlib --disable-multilib --enable-languages=c,c++
make -j 8 <== this may take around an hour or more to finish
(depending on your cpu speed)
make install
Tested under CentOS 7.8.2003 for gcc 9.3 and gcc 10.1
Tested under CentOS 8.1.1911 for gcc 10.1 (may take more time to compile)
Results: gcc/g++ 9.3.0/10.1.0
Installing gcc 7.4 (gcc 7.4.0) - released December 6, 2018:
Download file: https://ftp.gnu.org/gnu/gcc/gcc-7.4.0/gcc-7.4.0.tar.gz
Compile and install:
//required libraries:
yum install libmpc-devel mpfr-devel gmp-devel
./configure --with-system-zlib --disable-multilib --enable-languages=c,c++
make -j 8 <== this may take around 50 minutes or less to finish with 8 threads
(depending on your cpu speed)
make install

1. This Stack Overflow answer will help to see how to verify the downloaded source file.
2. Use the option --prefix to install gcc to another directory other than the default one. The toplevel installation directory defaults to /usr/local. Read about gcc installation options
