## installation
Once installed and running the system can redeploy itself.
However initially you need to do this yourself.
### remove old versions of docker
(if it's a fresh install of linux there shouldn't be any)
```
sudo apt-get remove docker docker-engine docker.io
```
### install docker
```
sudo apt install docker.io
```
### add current user to docker group
logout and back in afterwards
```
sudo usermod -aG docker $USER
```
### start and enable docker
```
sudo systemctl start docker
sudo systemctl enable docker
```
### change ssh port to 2022
```
sudo vi /etc/ssh/sshd_config
```
change Port 2022
### allow root to ssh
```
sudo vi /etc/ssh/sshd_config
```
## set the root password
```
sudo passwd root
```
change PermitRootLogin yes
reboot
start a stack running gitea to host repository.
## stack
### labels
get nodes with
```
docker node ls
```
add label with
```
docker node update --label-add com.sigyl.git-stack=yes [node id]
```
### global environment
the following environment variables need to be defined (define your own values)
```
echo 'export SIGYL_STACK_ROOT=/stack/deploy' | sudo tee -a /etc/profile.d/sigyl-stack.sh
echo 'export SIGYL_STACK_NAME=stack' | sudo tee -a /etc/profile.d/sigyl-stack.sh
sh /etc/profile.d/sigyl-stack.sh
```
### make a folder and give yourself access
```
sudo mkdir -p $SIGYL_STACK_ROOT
cd /stack
sudo chown -R $USER:$USER $SIGYL_STACK_ROOT
```
### clone the repository
```
cd /stack
git clone https://sigyl.com/git/giles/stack.git $SIGYL_STACK_ROOT
cd $SIGYL_STACK_ROOT
git checkout home-deploy
```
### make certificates for the registry
these certificates will be in .ca and .certificates
where $REGISTRY_DOMAIN is the host where the stack will run it should be on the local subnet ie trafic should not have to go over the internet.
eg git.local-domain
```
cd $SIGYL_STACK_ROOT/certificates
sh ca.sh $REGISTRY_DOMAIN:5003
sh make-cert.sh $REGISTRY_DOMAIN registry
```
### make environment variables
```
export TITLE="SiGyl Ltd!"

### build images
```
sh build.sh $SIGYL_STACK_ROOT
```
### initial deploy of stack
```
cd $SIGYL_STACK_ROOT
docker stack deploy -c docker-compose-home.yml $SIGYL_STACK_NAME
```
### initialise postgres database
find postgres id as $ID
```
docker ps | grep stack_guacamole-postgresql.1
```
```
sh init-postgresql.sh $ID
```
## initialise mongo
get mongo id as $ID
```
docker ps | grep stack_chat-mongo.1
```
```
sh init-mongo-chat.sh $ID
```
### scale chat and ngrok and nginx
```
sh init-scale.sh stack
```
### create a gitea drone application
This might be on your local gitea or some other one.
set environment variables for it as follows (example values):
```
export DRONE_GITEA_SERVER=https://sigyl.com/git
export DRONE_GITEA_CLIENT_ID=38218ed5-cf18-47e7-1234-710173dae499
export DRONE_GITEA_CLIENT_SECRET=ytsgdyXI_6zUrqwsI1wsssBAaUcsp27EyecT4nk5fA=
```
### redeploy
```
docker stack deploy -c docker-compose-home.yml $SIGYL_STACK_NAME
sh init-scale.sh stack
```

## docker-exec-runner on windows
These instructions are not very good...
https://exec-runner.docs.drone.io/installation/windows/
download and unpack on linux with
```
curl -L https://github.com/drone-runners/drone-runner-exec/releases/latest/download/drone_runner_exec_windows_amd64.tar.gz | tar zx
```
rename drone-runner-exec to drone-runner-exec.exe
make directory c:\Drone\drone-runner-exec on windows
copy drone-runner-exec.exe to directory
make config file with
```
DRONE_RPC_PROTO=https
