In github, EOS has already give a Dockfile to run eos in Docker. Also you could develop EOS in Docker with litter change：
1 clone eos github in your local path
git clone https://github.com/EOSIO/eos.git —recursive
2 don’t build eos when build docker image, and change the image entrypoint
- remove following lines in eos/Docker/Dockerfile
-COPY . /tmp/eos/
-RUN cd /tmp/eos/build && cmake -DWASM_LLVM_CONFIG=/opt/wasm/bin/llvm-config -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -DCMAKE_INSTALL_PREFIX=/opt/eos ../
- && make -j$(nproc) && make install && mv ../contracts /
- && ln -s /opt/eos/bin/eos* /usr/local/bin
- && rm -rf /tmp/eos*
- change the entry point
-ENTRYPOINT ["/sbin/entrypoint.sh"]
+ENTRYPOINT ["/bin/bash"]
3 build docker image in eos/Docker
docker build -t eosio/eos -f Docker/Dockerfile .
4 run docker image
docker run -it -v /local/path/to/eos:/tmp/eos eosio/eos
5 build eos in docker container's bash
mkdir -p /tmp/eos/installpath/data-dir && cd /tmp/eos && mkdir build && cd build
&& WASM_LLVM_CONFIG=/opt/wasm/bin/llvm-config cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -DCMAKE_INSTALL_PREFIX=/tmp/eos/installpath ../
&& make -j$(nproc) && make install
After the built finished, the eos will be install in /tmp/eos/installpath.
6 run EOS in the docker’s bash.
- copy config.ini and genesis.json
cp /tmp/eos/Docker/config.ini /tmp/eos/genesis.json /tmp/eos/installpath/data-dir
- change genesis.jso path in config.ini
genesis-json = "/tmp/eos/installpath/data-dir/genesis.json”
- run docker
cd /tmp/eos/installpath && bin/eosd --data-dir ./data-dir
With this eos image, you can change the eos code in you local machine, and rebuild the EOS in the docker container. The build result will exist in your local machine.
