# 多平台构建

# 第一步：

# docker buildx create --name mybuilder --use

# 第二步（本地测试）：

# VERSION=1.6.1.6
# docker buildx build \
#     --platform linux/arm64 \
#     -t doxwant/gotab:${VERSION} \
#     -t doxwant/gotab:latest \
#     --load \
#     --no-cache \
#     .

# 第三步（多平台构建推送）：

# VERSION=1.6.1.6
# docker buildx build \
#     --platform linux/amd64,linux/arm64 \
#     -t doxwant/gotab:${VERSION} \
#     -t doxwant/gotab:latest \
#     --push \
#     --no-cache \
#     .
