+# Docker-based build
+
+
+Base image taken from here: https://github.com/jc21/docker-rpmbuild-centos6
+
+```
+cd builder/build
+
+```
+
+
+Build and tag the docker file:
+```
+cd docker/
+docker build . -t my-rpmbuild-centos6
+cd ..
+```
+
+Run the build on a single spec file (Using devtoolset-7)
+```
+docker run --name rpmbuild-centos6 -v `pwd`:/home/rpmbuilder/rpmbuild --rm=true my-rpmbuild-centos6 /bin/build-spec-devtoolset-7.sh /home/rpmbuilder/rpmbuild/SPECS/gdal.spec
+```
+
+
+Build single spec file without devtoolset-7:
+```
+docker run --name rpmbuild-centos6 -v `pwd`:/home/rpmbuilder/rpmbuild --rm=true my-rpmbuild-centos6 /bin/build-spec /home/rpmbuilder/rpmbuild/SPECS/some.spec
+```
+
+Build all spec files in `SPECS`:
+
+```
+docker run --name rpmbuild-centos6 -v `pwd`:/home/rpmbuilder/rpmbuild --rm=true my-rpmbuild-centos6 /bin/build-all
+```
