## echo -e "$DOCKER_CA_PEM" | tr ',' '\n' | sed 's/"//' | head -c -1 > $HOME/.docker/ca.pem

echo DOCKER_CA_PEM=\"$(cat ca.pem | tr '\n' ',')\" >> deployment.env
echo DOCKER_CERT_PEM=\"$(cat cert.pem | tr '\n' ',')\" >> deployment.env
echo DOCKER_KEY_PEM=\"$(cat key.pem | tr '\n' ',')\" >> deployment.env
echo DOCKER_TLS_VERIFY=1 >> deployment.env
