Docker images are not official ASF releases but provided for convenience. Recommended usage is always to build the source.
# Assign Apache release version number to variable `APISIX_VERSION`, for example: 2.2. The latest version can be find at `https://github.com/apache/apisix/releases` APISIX_VERSION=2.2 docker build -t apisix:${APISIX_VERSION}-alpine --build-arg APISIX_VERSION=${APISIX_VERSION} -f alpine/Dockerfile alpine
docker build -t apisix:master-alpine -f alpine/Dockerfile alpine
