I installed libpcap in my container using below docker file using docker file below. How do I make sure it was installed and working as expected?
I tried below with the hope to see libpcap
D:\work >docker exec -u 0 -it containerId sh
/app # cd /etc/apk
/etc/apk # cat repositories
http://dl-cdn.alpinelinux.org/alpine/v3.8/main
http://dl-cdn.alpinelinux.org/alpine/v3.8/community
/etc/apk #
Below is my docker file
FROM mcr.microsoft.com/dotnet/core/sdk:2.2-alpine AS build
# Install packages
RUN apk update
RUN apk -U --no-cache add libpcap
Running the apk info command has below output

I can see libcap in the output.
If you still can't see the package. Make sure you have run apk update before installing libcap
