docker - 无法使用前端 xxx : rpc error: code = Unknown desc = (. ..) 解决: `exit status 2: gpg: decryption failed: No secret key`

Question

我想使用 Docker BuidlKit 的一项实验性功能 (mount=type=cache)

我的 Dockerfile 的第一行是:

    # syntax=docker/dockerfile:experimental    FROM i386/debian:buster    #    # Setup an apt cache for Docker (experimental)    #    RUN rm -f /etc/apt/apt.conf.d/docker-clean; echo 'Binary::apt::APT::Keep-Downloaded-Packages "true";' > /etc/apt/apt.conf.d/keep-cache    RUN --mount=type=cache,target=/var/cache/apt --mount=type=cache,target=/var/lib/apt apt update && apt-get --no-install-recommends install -y gcc

我已经为 docker 设置了一个密码存储，成功登录到 docker hub，我的 PATH 中的“docker-credential-pass”二进制文件，设置“使用加密密码的 docker 登录过程”。(如中所述

"How to Enable Docker Experimental Features and Encrypt Your Login Credentials"

    kalou@shinwey $ pass list    Password Store    `-- docker-credential-helpers        |-- xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx        |   `-- berryamin        `-- docker-pass-initialized-check

但是当我启动镜像构建时，该过程失败并显示:

有人可以帮助解释这里缺少什么吗？

尝试先下载 docker 镜像并运行构建镜像的命令，它对我有用
