apk tool gives permission denied

Question

I get this error message running alpine linux in a docker container hosted by Ubuntu 18.04 in Vagrant with its host in turn being Windows 10 behind a proxy. I have set the proxy variables but still get the same error.

/ # apk update
fetch http://dl-cdn.alpinelinux.org/alpine/v3.8/main/x86_64/APKINDEX.tar.gz
ERROR: http://dl-cdn.alpinelinux.org/alpine/v3.8/main: Permission denied
WARNING: Ignoring APKINDEX.adfa7ceb.tar.gz: No such file or directory

WARNING: Ignoring APKINDEX.efaa1f73.tar.gz: No such file or directory

What can I do?

Solution

I was getting the same symptoms until I followed the steps in Docker network config.

• vi ~/.docker/config.json
• Add a proxies json section updated with your details: , "proxies": { "default": { "httpProxy": "http://your-proxy-host:your-proxy-port", "noProxy": "*.test.example.com,.example2.com" } }

Make sure you include the protocol (http://) in the httpProxy setting, i.e.:

• "httpProxy": "*http://*your-proxy-host..."

not

• "httpProxy": "your-proxy-host..."

Once I did this, my Permission denied errors disappeared and the fetches were successful.
