Question

我在docker build上遇到以下错误

错误：无法锁定数据库：权限被拒绝错误：无法打开apk数据库：权限被拒绝

奇怪的是，APK ADD的第一部分工作正常：

Step 31/41 : RUN apk add --no-cache         bash         ca-certificates         openjdk11-jre-headless         tzdata
     tini         xmlstarlet     && wget -O  /usr/local/bin/wait-for-it.sh       "https://raw.githubusercontent.com/vishnubob/wait-for-it/a454892f3c2ebbc22bd15e446415b8fcb7c1cfa4/wait-for-it.sh" --no-check-certificate     && chmod +x /usr/local/bin/wait-for-it.sh

但是第二部分没有：

Step 36/41 : RUN apk add openssh      && echo "root:Docker!" | chpasswd
 ---> Running in 5626e233c96d
ERROR: Unable to lock database: Permission denied
ERROR: Failed to open apk database: Permission denied

我的docker文件在下面

Answer 1

USER camunda
...
RUN apk add openssh

camunda用户无法安装apk软件包，但没有安装权限。切换用户之前，请安装所有软件包。或者稍后，根据您要做什么设置CMD之前切换用户。或添加sudo并将NOPASSWD awk添加到sudoers的{{1}}文件中，并用camunda完成。无论哪种方法-确保您具有运行sudo并遵循apk的权限。
