Using LXD for local development

1. Create a personal SSH key

2. Create a profile

   lxc profile list  # shows all available profiles
   lxc profile show <profile-name>  # shows profile details
   

3. Create an lxc container with the default and ricardo profiles

The ricardo lxc profile will setup:

• Correct mappings for being able to access ~/dev from the host
• Passworldess sudo
• Import the SSH key associated with ricardogsilva from github

For container names, use the following format:

   <project_code>-dev

   container_base=ubuntu:16.04
   container_name=test-dev

   lxc launch \
       ${container_base} \
       ${container_name} \
       -p default \
       -p ricardo

1. Get the IP of the newly created container with lxc list

2. Setup an SSH config for easy login. Edit ~/.ssh/config with something like:

   cat << EOF >> ~/.ssh/config
   
   Host <project_code-dev>
      HostName <container IP>
      User ricardo
      IdentityFile ~/.ssh/ricardo_silva
   
   EOF
   

3. SSH into the container and do some updates. If needed, add the ubuntugis ppa too:

   ssh <project_code-dev>
   sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
   sudo apt update && sudo apt upgrade --yes
   
   4. Update locales
   
   5. Add `~/.profile` and `~/.bashrc` files
   
   6. Now install project specific stuff, e.g.:
   
   

sudo apt install –yes
openjdk-8-jre

7. If using postgresql, tweak the relevant settings files to allow external
   access

# sudo vim /etc/postgresql/9.5/main/postgresql.conf listen_addresses = ‘*’

# sudo vim /etc/postgresql/9.5/main/pg_hba.conf host all all 10.0.1.0/24 md5

# reload postgres server sudo systemctl reload postgresql

   ```psql
   # create a user and database
   CREATE USER <project_code> WITH PASSWORD '<project_code>';
   CREATE DATABASE <project_code> WITH OWNER '<project_code>';
   \c <project_code>
   CREATE EXTENSION postgis;

Useful lxc commands

lxc list  # show current containers, along with their IP
lxc profile list  # list available profiles
lxc profile show <profile>  # show profile details
