Alpine fix; plus 1 #8821

johnbeisner · 2018-03-16T20:03:16Z

The '-n' option to 'cp' does not exist for Alpine [try "-u"]
Don't use "$ID.$VERSION_ID" for the error message

Addresses: https://github.com/dotnet/cli/issues/8738
CP options for Alpine:
From: http://www.spblinux.de/2.0/doc/cp.html
-a Same as -dpR
-d Preserve links
-p Preserve file attributes if possible
-R Copy directories recursively

…RSION_ID" for the error message.

@janvorli
Do you have an Alpine that we can try this on?

janvorli · 2018-03-16T20:24:04Z

@johnbeisner yes, I do, will test it soon.

When I use Alpine 3.6, I see some additional options on cp.

BusyBox v1.26.2 (2017-11-23 08:40:54 GMT) multi-call binary.

Usage: cp [OPTIONS] SOURCE... DEST

Copy SOURCE(s) to DEST

	-a	Same as -dpR
	-R,-r	Recurse
	-d,-P	Preserve symlinks (default if -R)
	-L	Follow all symlinks
	-H	Follow symlinks on command line
	-p	Preserve file attributes if possible
	-f	Overwrite
	-i	Prompt before overwrite
	-l,-s	Create (sym)links
	-u	Copy only newer files

Would -u be an adequate replacement for -n?

janvorli · 2018-03-16T21:02:22Z

@johnbeisner the script seems to work on Alpine, there is just one warning:

DOTNET_INSTALL_SKIP_PREREQS=1 ./dotnet-install.sh --version 2.1.300-preview2-008251

@natemcmaster
"Would -u be an adequate replacement for -n?" - do all Alpine boxes have BusyBox v1.26.2?

natemcmaster · 2018-03-16T21:33:31Z

I'm not sure. The only way I've used Alpine is via Docker. docker run --rm -it alpine:3.6 cp --help

janvorli · 2018-03-16T22:14:56Z

@johnbeisner it still works ok.

johnbeisner · 2018-03-16T22:15:42Z

@janvorli
May I see the verbose output?

LGTM

It works on Alpine 3.6 with DOTNET_INSTALL_SKIP_PREREQS=1 ./dotnet-install.sh, but it does NOT work on latest Alpine 3.7, released in Nov 2017..
If I manually install 3.6 tarball on latest 3.7, then Console, Lib and MVC apps all work fine. So RID detection should be flexible (https://github.com/dotnet/core-setup/issues/3817).

Secondly, it would be nice to have a portable (non-GNU) way of finding the libs, instead of ldconfig, so we don't have to set DOTNET_INSTALL_SKIP_PREREQS.

@kasper3
"but it does NOT work on latest Alpine 3.7" - the install script does not support Alpine 3.7; we build an Alpine 3.6* specific asset: dotnet-sdk-2.1.300-preview2-008251-alpine.3.6-x64.tar.gz we do not create a Alpine 3.7 asset.

ghost · 2018-03-16T23:05:00Z

@johnbeisner, there is no alpine 3.6 specific asset as I mentioned earlier. You should really give manual install a try (max time 3 minutes if you have docker installed)

docker run -it alpine:latest
# or alpine:3.7

# in container
apk update
apk add curl libstdc++ libunwind libintl icu-libs openssl

curl -O https://dotnetcli.blob.core.windows.net/dotnet/Sdk/master/dotnet-sdk-latest-alpine.3.6-x64.tar.gz
mkdir -p /usr/bin/dotnet
tar -xzvf dotnet-sdk-latest-alpine.3.6-x64.tar.gz  -C /usr/bin/dotnet
export PATH=$PATH:/usr/bin/dotnet
rm dotnet-sdk-latest-alpine.3.6-x64.tar.gz

nugetConfDir="/root/.nuget/NuGet"
mkdir -p $nugetConfDir
cat > $nugetConfDir/NuGet.Config <<-"EOF"
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="dotnet-core" value="https://dotnet.myget.org/F/dotnet-core/api/v3/index.json" />
  </packageSources>
</configuration>
EOF

now you can do dotnet new console etc.

So the bug in this dotnet-install.sh script is the hardcoded 3.6..

@kasper3
Please advocate for: https://github.com/dotnet/core-setup/issues/3817 I believe that is the best use of your efforts to effect the change you would like to see.

ghost · 2018-03-16T23:19:35Z

OK thanks. Regarding this PR, is the proposed solution from dotnet/cli team for Alpine (any version) is to set DOTNET_INSTALL_SKIP_PREREQS=1, since ldconfig usage is not functional on Alpines (and https://github.com/dotnet/cli/issues/8792 was closed)?

johnbeisner · 2018-03-16T23:26:27Z

@kasper3
For now - yes, but we reserve the right to improve the user experience over time.

The '-n' option to 'cp' does not exist for Alpine; don't use "$ID.$VE…
