# ollama-gfx906/Dockerfile
#
# Custom ollama image with ROCm 6.1 + gfx906 (MI50) support.
# The official ollama/rocm image ships ROCm 7.2 which dropped gfx906.
# This uses v0.23.2's native CMake build system with AMDGPU_TARGETS including gfx906.
#
# Build: docker build -t ollama/ollama:rocm-gfx906 ai/ollama
