RemoteLabz's front update guide¶

Save your .env file¶

All configuration variables are saved in the file .env.local or if you don't have this file, in the file .env If you don't have a .env.local, save your .env to .env.local

sudo -u remotelabz cp .env .env.local

Update the code¶

cd /opt/remotelabz-worker
git fetch
git pull

Info

To choose a specific version :

git checkout tags/2.X.Y

or a branch

git checkout dev

Compare your .env.local file with the .env file to be sure we have the same parameters defined

sudo composer update
sudo php bin/console cache:clear
sudo chown remotelabz-worker:www-data * -R
sudo chmod g+w /opt/remotelabz-worker/var -R
sudo systemctl daemon-reload
sudo service remotelabz-worker restart

cd ~
git clone https://github.com/tsl0922/ttyd.git
cd ttyd && mkdir build && cd build

sudo lxc-create -t download -n Debian -- -d debian -r bullseye -a amd64 --keyserver hkp://keyserver.ubuntu.com;
sudo lxc-create -t download -n Ubuntu20LTS -- -d ubuntu -r focal -a amd64 --keyserver hkp://keyserver.ubuntu.com;
sudo lxc-create -t download -n Alpine3.15 -- -d alpine -r 3.15 -a amd64 --keyserver hkp://keyserver.ubuntu.com;
sudo su;
echo "nameserver 1.1.1.3" > "/var/lib/lxc/Migration/rootfs/etc/resolv.conf";
