无法创建deno码头图像

Question

我想使用Dockerfile创建deno码头映像

FROM alpine:latest

WORKDIR /

RUN apk update && \
    apk upgrade

RUN apk add curl

RUN curl -fsSL https://deno.land/x/install/install.sh | sh

ENV DENO_INSTALL="/root/.deno"

ENV PATH="${DENO_INSTALL}/bin:${PATH}"

RUN deno --help

但是当运行docker build -t deno .时，它最终显示了/bin/sh: deno: not found

Answer 1

Alpine缺少运行deno所需的glibc。

您可以使用frolvlad/alpine-glibc:alpine-3.11_glibc-2.31代替，它会工作得很好。

FROM frolvlad/alpine-glibc:alpine-3.11_glibc-2.31

WORKDIR /

RUN apk update && \
    apk upgrade

RUN apk add curl

RUN curl -fsSL https://deno.land/x/install/install.sh | sh

ENV DENO_INSTALL="/root/.deno"

ENV PATH="${DENO_INSTALL}/bin:${PATH}"

RUN deno --help

我建议构建一个特定的deno版本，为此，您应该使用：

curl -fsSL https://deno.land/x/install/install.sh | sh -s v1.0.0

FROM frolvlad/alpine-glibc:alpine-3.11_glibc-2.31

ENV DENO_VERSION=1.0.0

# ...

RUN curl -fsSL https://deno.land/x/install/install.sh | sh -s v${DENO_VERSION}

# ...
