1 Build docker image

1. update the base image

```sh
docker images
docker pull archlinux:base-devel
docker images # list images again
# Remove all dangling images
docker image prune
```

2. build the image

```sh
docker build -f Dockerfile.dev.build -t zane/dev .
```

2 How to use this docker image

- create a docker volume if you want it

```sh
docker volume create nvim_red_duck
```

2.1 docker compose lifecycle

2.1.1 creating and starting a container

0. the env file

• rename .env.example to .env
• fill .env file with your dir info.

1. start docker compose services

cd nvim-nvchad-dockerize
# using .env file
docker-compose run --service-ports dev
# or using another env file
docker-compose --env-file <.env.example> run --service-ports dev

then, the nvim container is creaded and login the shell.

2. connect to the container in other terms

# get the id of nvim container
docker ps -a
docker exec -it <the nvim container id> bash

4. exit in the first term and docker rm ...

2.1.2 starting an exited container

docker start -ai <exited container id>
docker exec -it <running container id> bash

2.2 docker lifecycle without docker compose

2.2.1 start a new container in the first term

docker run -it -p 3000:3000 -p 4000:4000 -p 8000:8000 -p 9000:9000 -v c:\a:/home/nv/a -v c:\Users\username\.ssh:/home/nv/.ssh -v "//var/run/docker.sock:/var/run/docker.sock" zane/dev

sudo chmod 600 /home/nv/.ssh/config

2.2.2 start a exited container

docker start -ai <exited container id>

2.2.3 connect to the running container

docker exec -it <running container id> bash

# as root
docker exec -u 0  -it <running container id> bash

2.2.4 exit in the first term and docker rm ...

2.3 After a contain first running

2.3.1 init nvim

1. start nvim, then :qa
2. start nvim, then :checkhealth

2.3.2 update nvchad if you want

<lead> + u + u

2.3.3 Go to 5 Git info init

3 Arch linux notes

3.1 set mirrorlist

# in docker # as root
reflector -f 5 --country 'United States' --protocol https --sort rate  --download-timeout 2 --save /etc/pacman.d/mirrorlist

reflector -f 5 --country 'United States' \
--protocol https \
--sort rate \
--download-timeout 2 \
--completion-percent 100 \
--save /etc/pacman.d/mirrorlist

4 Docker volume backup

4.1 cp "old_volume" to "new_volume"

docker volume create --name new_volume

docker container run --rm -it \
           -v old_volume:/from \
           -v new_volume:/to \
           alpine ash -c "cd /from ; cp -av . /to"

5 Git info init

git init .

# change to the main branch
git config --global init.defaultBranch <main>
git branch -m <main>

# project settings, not globle
git config user.name <"monster">
git config user.email <"i@monster">
git remote -v

# edit the git settings file
git config --global --edit

using a key for git in shell

GIT_SSH_COMMAND="ssh -i ~/.ssh/a_private_key" git push origin main

6 Windows WSL2

6.1 restart WSL2 for vmmem process

1. shoutdown WSL

6.2 free memeory >2GB by closing WSL2 and docker for other heavy app

1. close docker desktop
2. shoutdown WSL2

7 Windows 10

# windows
rd -r ~\AppData\Local\nvim
rd -r ~\AppData\Local\nvim-data

choco install neovim
