You can also use the OpenAlias p2pool.observer directly on the GUI.

Operational instructions

A docker compose setup is provided and documented.

If desired each tool can be run individually, but that is left to the user to configure, refer to Docker setup as reference.

Requirements

• docker compose or similar
• git installed
• Disk space for new incoming historic data. Assume a few tens of MiB per day
• A monerod non-pruned node running in unrestricted mode preferably, but can work with restricted mode.
• Enough RAM to fit state and incoming queries. It can run with lower with adjustment of settings, but 8 GiB per instance should be fine.

Initial setup

$ git clone https://git.gammaspectra.live/P2Pool/observer.git test-instance
$ cd test-instance
$ cp .env.example .env

Edit .env via your preferred editor, specifically around the monerod host options and generate keys for the Tor hidden service.

If you want to make changes to additional docker compose settings, do not edit docker-compose.yml. Instead, create docker-compose.override.yml and place new settings there. See Multiple Compose files documentation.

Update / Apply new settings

Within the instance folder, run this command

$ git checkout -- '*/default.pgo'; \
git pull && \
docker compose build --pull && \
docker compose up -d && \
docker compose restart tor site

docker compose restart tor is necessary due to the tor server not refreshing DNS of the containers.

It is recommended to run docker system prune regularly or after update to cleanup no longer used images.

Development notes

Requires using CGO when running the main modes where RandomX hashes are used, but can be used with CGO_ENABLED=0 specifically as a library.

You can install the RandomX dependency via this command:

$ git clone --depth 1 --branch master https://github.com/tevador/RandomX.git /tmp/RandomX && cd /tmp/RandomX && \
    mkdir build && cd build && \
    cmake .. -DCMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX:PATH=/usr && \
    make -j$(nproc) && \
    sudo make install && \
    cd ../ && \
    rm -rf /tmp/RandomX

To generate web templates, run this command:

$ go run github.com/valyala/quicktemplate/qtc@v1.7.0
