Questions[alpine](server)

I want to install Bazel (version 5.1.1) into an Alpine container using apk.

I tried this command and got this error:

% apk add bazel=5.1.1
ERROR: unable to select packages:
  bazel (no such package):
    required by: world[bazel=5.1.1]

Removing the version doesn't help...

% apk add bazel
ERROR: unable to select packages:
  bazel (no such package):
    required by: world[bazel]

Adding "--no-cache" to the apk command also doesn't help.

Can anyone explain the cause of the error and how to make the installation happen correctly?

I have a wireguard installed on a Alpine server. It's working, but when I reboot the server, I'm obliged to manually execute wg-quick up wg0

wireguard:~# wg show
wireguard:~# wg-quick up wg0

Where is my mistake?

While attempting to clone a remote Git repo using SSH I got the following error:

git clone user@remote-repo:project.git .
remote: Counting objects: 187444, done.
remote: Compressing objects: 100% (73430/73430), done.
client_loop: send disconnect: Broken pipe.06 MiB | 4.04 MiB/s
fetch-pack: unexpected disconnect while reading sideband packet
fatal: early EOF
fatal: index-pack failed

My environment has the following Specs:

• WSL2 (Windows Subsystem 4 Linux)
• git --version git version 2.30.1

The git package can be found here https://pkgs.alpinelinux.org/package/edge/main/x86_64/git

uname -a
Linux 4.19.128-microsoft-standard #1 SMP Tue Jun 23 12:58:10 UTC 2020 x86_64 Linux

2021-03-09-07:11AM wsl@Alpine:~$ more /etc/issue
Welcome to Alpine Linux 3.10
Kernel \r on an \m (\l)

I've got no clue why is this happening. Is it a bursting or kernel configuration issue on Alpine? WSL? I doubt it's the remote host. The remote host works fine for SSH, as well as cloning for every non-WSL user.

Is it possible to list packages directly installed by apk add? e.g. apk add docker, apk add lm-sensors file, etc.

Running apk info lists ALL installed packages (including dependencies of installed packages), but I want to narrow this list down to top-level packages that are not dependencies of other packages in order to reproduce these packages on another system.

This used to work to set the timezone. I have a container on Alpine 3.9.4 where it worked:

RUN apk add --no-cache tzdata
ENV TZ America/Chicago
RUN apk del tzdata

I'm now creating a Docker container with Alpine Linux v3.10.3, and it doesn't work anymore. A user suggested that I need to copy to /etc/localtime:

RUN apk add --no-cache tzdata
ENV TZ America/Chicago
RUN cp /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
RUN apk del tzdata

Neither of these work if tzdata is removed. However, they work if tzdata is not removed. Why is this?
