This is the base image for lncm/bitcoind Docker images that rely on Berkeleydb version db-4.8.30.NC. This stage is separated from the main bitcoind build process for two reasons:

1. BDB never changes and is only useful when bitcoind is compiled with wallet support enabled,
2. qemu-emulated builds take a very long time, separating out this part of the build helps save precious minutes.

Images here are built for three architectures: amd64, arm32v7 , and aarch64 (aka arm64v8). The latter two are built using qemu emulation. For details see here.

Pulling this image directly is only useful if you know exactly what you need it for, can be achieved with:

docker pull lncm/berkeleydb:v4.8.30.NC

NOTE: architecture is chosen automatically based on the CPU of the Docker host.

To manually specify the architecture, use one of the commands below.

docker pull lncm/berkeleydb:v4.8.30.NC-amd64
docker pull lncm/berkeleydb:v4.8.30.NC-arm32v7
docker pull lncm/berkeleydb:v4.8.30.NC-arm64v8

To build bitcoind w/o the need to rebuild Berkeleydb, you can do:

# Start new stage to build _something_
FROM alpine AS something

# Copy all BDB relevant files to your stage
COPY  --from=lncm/berkeleydb:v4.8.30.NC  /opt  /opt

# …
