archlinux lxc debian centos container

Create Debian8 and CentOS7 LXC containers on Archlinux host

Using LXC to create Debian 8 and CentOS 7 containers require to play with AUR.

In order to ease the work:

# pacman -S base-devel

In  /etc/pacman.conf
[archlinuxfr]
SigLevel = Never
Server = http://repo.archlinux.fr/$arch

# pacman -S lxc arch-install-scripts netctl
# pacman -S yaourt
$ yaourt -S debootstrap yum

This last command will pull several packages from AUR then expect some long time compiling
I dont really know why, but I had to reboot to have everything working smoothly.

Create a CentOS7 container


# export CONTAINER_NAME=c7-00
# lxc-create  -t centos --name ${CONTAINER_NAME} -- --release 7 --arch x86_64 \
               --repo YOU_CUSTOM_REPO

Then edit the configuration:
# nano -w /var/lib/lxc/${CONTAINER_NAME}/config

Mine looks like this

lxc.rootfs = /var/lib/lxc/c7-00/rootfs
lxc.include = /usr/share/lxc/config/centos.common.conf
lxc.arch = x86_64
lxc.utsname = c7-00
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.name = eth0
lxc.network.ipv4 = 192.168.128.130/23
lxc.network.ipv4.gateway = 192.168.128.1
lxc.network.hwaddr = 9e:32:da:11:44:5e

Start the container with the previous settings:
# lxc-start --name ${CONTAINER_NAME}

Enter the container
# lxc-attach --name ${CONTAINER_NAME}

# export PATH="/sbin:"${PATH}
# yum install -y nano

Install a Debian8 container

# export CONTAINER_NAME=b7-00
# lxc-create  -t debian --name ${CONTAINER_NAME} -- --mirror=YOUR_MIRRORdebian/ \
      --release=jessie --security-mirror=YOUR_MIRROR/debian-security/ --arch=x86_64

Then edit the configuration:
# nano -w /var/lib/lxc/${CONTAINER_NAME}/config

Mine looks like this

lxc.rootfs = /var/lib/lxc/d8-00/rootfs
lxc.include = /usr/share/lxc/config/debian.common.conf
lxc.utsname = d8-00
lxc.arch = amd64
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.name = eth0
lxc.network.ipv4 = 192.168.128.128/23
lxc.network.ipv4.gateway = 192.168.128.1
lxc.network.hwaddr = 9e:32:da:11:44:5a

Start the container with the previous settings:
# lxc-start --name ${CONTAINER_NAME}

Enter the container
# lxc-attach --name ${CONTAINER_NAME}

# export PATH="/usr/sbin:/sbin:/bin:"${PATH}

Undefined global vim

Defining vim as global outside of Neovim When developing plugins for Neovim, particularly in Lua, developers often encounter the "Undefined global vim" warning. This warning can be a nuisance and disrupt the development workflow. However, there is a straightforward solution to this problem by configuring the Lua Language Server Protocol (LSP) to recognize 'vim' as a global variable. Getting "Undefined global vim" warning when developing Neovim plugin While developing Neovim plugins using Lua, the Lua language server might not recognize the 'vim' namespace by default. This leads to warnings about 'vim' being an undefined global variable. These warnings are not just annoying but can also clutter the development environment with unnecessary alerts, potentially hiding other important warnings or errors. Defining vim as global in Lua LSP configuration to get rid of the warning To resolve the "Undefined global vi...

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter. npm run build --base-href='https://ngx.rktmb.org/foo did not set the base href in indext.html After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo...

CopilotChat GlobFile Configuration

CopilotChat GlobFile Configuration Want to feed multiple files into GitHub Copilot Chat from Neovim without listing each one manually? Let's add a tiny feature that does exactly that: a file glob that includes full file contents . In this post, we'll walk through what CopilotChat.nvim offers out of the box, why the missing piece matters, and how to implement a custom #file_glob:<pattern> function to include the contents of all files matching a glob. Using Copilot Chat with Neovim CopilotChat.nvim brings GitHub Copilot's chat right into your editing flow. No context switching, no browser hopping — just type your prompt in a Neovim buffer and let the AI help you refactor code, write tests, or explain tricky functions. You can open the chat (for example) with a command like :CopilotChat , then provide extra context using built-in functions. That “extra context” is where the magic really happens. Built-in functio...
