[英]alpine linux apk installation error in Dockerfile
I am trying to execute the following code in a Dockerfile :我正在尝试在Dockerfile中执行以下代码:
FROM alpine:3.7
RUN apk update && apk add --no-cache busybox musl prometheus-node-exporter
RUN rc-update add prometheus-node-exporter default
RUN rc-service prometheus-node-exporter start
RUN echo " - job_name: node \
# If prometheus-node-exporter is installed, grab stats about the local \
# machine by default. \
static_configs: \
- targets: ['localhost:9100', 'alpine_distro:9100']" >> /etc/prometheus/prometheus.yml
but my build returns the following error:但我的构建返回以下错误:
ERROR:
unsatisfiable constraints:
prometheus-node-exporter (missing):
required by: world[prometheus-node-exporter]
The command '/bin/sh -c apk update && apk add --no-cache busybox musl prometheus-node-exporter' returned a non-zero code: 1
I am not used to Alpine package manager but my guess is that I might not be using a repo that contains prometheus-node-exporter
?我不习惯 Alpine package 管理器,但我的猜测是我可能没有使用包含
prometheus-node-exporter
存储库?
Or am I missing something else?还是我错过了其他东西?
If from some reason you're forced to use Alpine 3.7, you could install the prometheus-node-exporter
package from the Alpine 3.13 community repo:如果由于某种原因您被迫使用 Alpine 3.7,您可以从 Alpine 3.13 社区 repo 安装
prometheus-node-exporter
package:
$ sudo docker run -it alpine:3.7
/ # apk add prometheus-node-exporter --repository=http://dl-cdn.alpinelinux.org/alpine/v3.13/community
fetch http://dl-cdn.alpinelinux.org/alpine/v3.13/community/x86_64/APKINDEX.tar.gz

It seems node_exporter
only depends on musl, so it's likely to work well without special issues:似乎
node_exporter
只依赖于 musl,所以它很可能在没有特殊问题的情况下运行良好:
/ # ldd /usr/bin/node_exporter
/lib/ld-musl-x86_64.so.1 (0x7fea4c68a000)
libc.musl-x86_64.so.1 => /lib/ld-musl-x86_64.so.1 (0x7fea4c68a000)
However, if you have that option, it's recommended to upgrade your base Alpine version to 3.13, instead.但是,如果您有该选项,建议您将基本 Alpine 版本升级到 3.13。
