Question

我正在尝试将docker镜像迁移到基于alpine的镜像，但是遇到一个问题，我无法在镜像构建期间编译消息。

FROM python:3.6-alpine
ENV PYTHONUNBUFFERED 1

# Creating working directory
RUN mkdir /code
WORKDIR /code

# Copying requirements
COPY ./myproject/ .

RUN apk add --no-cache --virtual .build-deps \
ca-certificates gcc postgresql-dev linux-headers musl-dev \
libffi-dev jpeg-dev zlib-dev \
&& pip install -r requirements.txt \
&& find /usr/local \
    \( -type d -a -name test -o -name tests \) \
    -o \( -type f -a -name '*.pyc' -o -name '*.pyo' \) \
    -exec rm -rf '{}' + \
&& runDeps="$( \
    scanelf --needed --nobanner --recursive /usr/local \
            | awk '{ gsub(/,/, "\nso:", $2); print "so:" $2 }' \
            | sort -u \
            | xargs -r apk info --installed \
            | sort -u \
)" \
&& apk add --virtual .rundeps $runDeps \
&& apk del .build-deps

RUN python manage.py compilemessages

我唯一的问题是在编译消息的步骤中。这里的错误

CommandError: Can't find msgfmt. Make sure you have GNU gettext tools 0.15 or newer installed.

Answer 1

您需要将gettext添加到dockerfile中。您可以使用：RUN apk add gettext进行添加。还有Alpine软件包链接：https://pkgs.alpinelinux.org/package/edge/main/x86/gettext

Answer 2

这是我在项目中使用的apline3.8的Dockerfile，它适用于makemessages和compilemessages。

FROM python:3.6-alpine3.8

# postgresql-client is required by psql
# postgresql-dev musl-dev gcc are required by psycopg
# NOTE: there is py3-psycopg2
# linux-headers is required by uwsgi
# gettext-dev is required by ./manage.py makemessages

# TODO: optimize installation by using --virtual
RUN apk update && apk upgrade \
    && apk add postgresql-client \
        postgresql-dev \
        musl-dev \
        gcc \
        linux-headers \
        gettext-dev \
    && pip install pipenv

ENV PYTHONUNBUFFERED=1 \
    PYTHONIOENCODING=UTF-8

COPY docker/backend/docker-entrypoint.sh /
ENTRYPOINT ["/docker-entrypoint.sh"]

WORKDIR /project/backend

COPY backend/Pipfile backend/Pipfile.lock /project/backend/

# TODO: use virtualenv?
RUN pipenv install --system --ignore-pipfile --dev

Answer 3

我知道这个答案很旧，但是希望我的答案会有所帮助。

您首先创建--virtual软件包并安装它们。这对您的容器非常有用，因为它既小又干净，但是问题在这里

&& apk del .build-deps

使用此命令删除所有虚拟软件包。如果gettext-dev在这里

RUN apk add --no-cache --virtual .build-deps \
ca-certificates gcc postgresql-dev linux-headers musl-dev \
libffi-dev jpeg-dev zlib-dev gettext-dev\

它也将被删除。因此，如果您希望软件包保留在容器中，则需要在安装主软件包后将其添加。

例如

FROM python:3.6-alpine
ENV PYTHONUNBUFFERED 1

# Creating working directory
RUN mkdir /code
WORKDIR /code

# Copying requirements
COPY ./myproject/ .

RUN apk add --no-cache --virtual .build-deps \
ca-certificates gcc postgresql-dev linux-headers musl-dev \
libffi-dev jpeg-dev zlib-dev \
&& pip install -r requirements.txt \
&& find /usr/local \
    \( -type d -a -name test -o -name tests \) \
    -o \( -type f -a -name '*.pyc' -o -name '*.pyo' \) \
    -exec rm -rf '{}' + \
&& runDeps="$( \
    scanelf --needed --nobanner --recursive /usr/local \
            | awk '{ gsub(/,/, "\nso:", $2); print "so:" $2 }' \
            | sort -u \
            | xargs -r apk info --installed \
            | sort -u \
)" \
&& apk add --virtual .rundeps $runDeps \
&& apk del .build-deps

RUN apk add gettext-dev

RUN python manage.py compilemessages

或者您可以删除此行

&& apk del .build-deps

但这意味着您的容器将更大。

Django-无法在Alpine中编译消息？
