`echo 'something' >> /etc/apk/repositories` results in permissions issue

[samlevin]

I'm trying to programmatically modify /etc/apk/repositories through the Vagrantfile generated by this repo. When I attempt via:

echo 'http://nl.alpinelinux.org/alpine/v3.3/main' >> /etc/apk/repositories'

I get the following: bash: /etc/apk/repositories: Permission denied

Prefixing the command with sudo doesn't appear to make a difference. Am I missing something obvious?

Use-case: Trying to install docker on an alpine vagrantbox (at provision time) using instructions here: https://wiki.alpinelinux.org/wiki/Docker

Thanks!

This Vagrantfile worked for me.

Vagrant.configure(2) do |config|
  config.vm.define "alpine" do |alpine|
    alpine.vm.box = "maier/alpine-3.5-x86_64"
    alpine.vm.synced_folder ".", "/vagrant", disabled: true
    alpine.vm.provider "virtualbox" do |vb|
      vb.name = 'Alpine'
      vb.cpus = 2
      vb.memory = 2048
      vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on", "--nic1", "nat", "--cableconnected1", "on"]
    end

    alpine.vm.provision 'shell', inline: <<-SHELL
        echo "Add community repository"
        echo 'http://dl-cdn.alpinelinux.org/alpine/edge/community' >> /etc/apk/repositories

        echo "Update repositories"
        apk update

        echo "Install docker package"
        apk add docker

        echo "Enable docker service"
        rc-update add docker boot

        echo "Start docker service"
        service docker start
    SHELL
  end
end

Here's one with alpine 3.3, if you need to stick with that version of alpine.

Vagrant.configure(2) do |config|
  config.vm.define "alpine" do |alpine|
    alpine.vm.box = "maier/alpine-3.3.1-x86_64"
    alpine.vm.synced_folder ".", "/vagrant", disabled: true
    alpine.vm.network "private_network", ip: "172.28.128.250"
    alpine.vm.synced_folder ".", "/vagrant", type: "nfs"
    alpine.vm.provider "virtualbox" do |vb|
      vb.name = 'Alpine'
      vb.cpus = 2
      vb.memory = 2048
      vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on", "--nic1", "nat", "--cableconnected1", "on"]
    end

    alpine.vm.provision 'shell', inline: <<-SHELL
        echo "Add community repository"
        echo 'http://dl-cdn.alpinelinux.org/alpine/v3.3/community' >> /etc/apk/repositories

        echo "Update repositories"
        apk update

        echo "Upgrade box"
        apk upgrade

        echo "Install docker package"
        apk add docker

        echo "Enable docker service"
        rc-update add docker boot

        echo "Start docker service"
        service docker start
    SHELL
  end
end

Worked like a charm. Thank you very much!
