  Docker Local Path Nginx


  Hello from Nginx container of `hostname`


EOF



docker run -d --name nginx-local \
-v $(pwd)/htdocs:/usr/share/nginx/html nginx

IPADDRESS=$(docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' nginx-local)
# Alternative with jq
# docker inspect nginx-local| jq -r '.[0].NetworkSettings.Networks.bridge.IPAddress'
curl $IPADDRESS

==== Start nginx with docker volumes ==== Prepare docker managed volume:


docker volume create htdocs-volume

docker container run \
    -v $(pwd)/htdocs:/htdocs \
    -v htdocs-volume:/htdocs1  \
    -ti --rm alpine /bin/sh
cp htdocs/index.html htdocs1
exit

Use docker managed volume:


docker run -d --name web-server \
-v htdocs-volume:/usr/share/nginx/html nginx

# check content
docker exec web-server ls /usr/share/nginx/html
docker run --rm -ti --volumes-from web-server alpine /bin/sh
ls /usr/share/nginx/html
exit

Inspect volumes:


docker volume ls
docker volume inspect htdocs-volume

#docker volume rm htdocs-volume

==== Start with mount options and publish nginx ====


docker run \
  --mount type=bind,src=$(pwd)/htdocs,dst=/usr/share/nginx/html,readonly \
  -p 8080:80 \
  nginx-public

==== Start local mysql ====


# hostpath bind mount
docker run --name mysql-db \
  -v $(pwd)/datadir:/var/lib/mysql
  -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:8.4.9

# Access DB

# Stop db
docker stop mysql.db
docker rm mysql-db

# or docker managed volume /var/lib/docker/volumes
docker volume create mysql-data
docker run --name mysql-db \
  -v mysql-data:/var/lib/mysql
  -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:8.4.9

sudo apt update
sudo apt install -y nfs-kernel-server

# Create the export directory
sudo mkdir -p /exports/shared
sudo chown nobody:nogroup /exports/shared
sudo chmod 755 /exports/shared

# add this to /etc/exports
sudo vi /etc/exports
/exports/shared    192.168.1.0/24(rw,sync,no_subtree_check,no_root_squash)


# Export the shares
sudo exportfs -ra

# Start and enable NFS server
sudo systemctl enable nfs-kernel-server
sudo systemctl start nfs-kernel-server

# Verify exports
sudo exportfs -v

Create docker volume with a NFS Share:


docker volume create \
  --driver local \
  --opt type=nfs \
  --opt o=addr=192.168.1.100,rw,nfsvers=4.1 \
  --opt device=:/exports/shared \
  shared-data

Use volume inside docker-compose service:


mkdir -p web
cd web
cat >docker-compose.yml <


Use nfs share with docker --mount directly:


docker run -d \
  --name web \
  --mount type=volume,volume-driver=local,\
volume-opt=type=nfs,\
volume-opt=o=addr=192.168.1.100,\
volume-opt=device=:/exports/shared,\
dst=/usr/share/nginx/html \
  nginx:alpine
