1: NO certificates:

The variable file <.env> must be modified depending on the environment (#CA, #Server, #General blocks)

Generate certificates:

chmod u+x ./*.sh
./generate-certificates.sh

Change Docker configuration:

./generate-config.sh

Copy certificates, rsyslog.conf to local folder (in case of using VOLUME '/etc/rsyslog-docker/'):

mkdir -p /etc/rsyslog-docker/pki/
cp ./rsyslog/config/rsyslog.conf /etc/rsyslog-docker/
cp ./rsyslog/certificates/<ca.crt.pem> ./rsyslog/certificates/<server.crt.pem> ./rsyslog/certificates/<server.key.pem> /etc/rsyslog-docker/pki/

Docker:

docker container stop $CONTAINER_NAME 
docker build --build-arg PATH_CONFIG=/config/ --build-arg PATH_CERT=/certificates/ -t $IMAGE_NAME .

#run
docker run -it --rm -h $SERVER_LOCAL --privileged --name $CONTAINER_NAME dev-syslog-tls
docker run -it --rm -h $SERVER_LOCAL --cap-add SYSLOG --privileged -v /var/logs:/var/log -p $TLS_PORT_HOST:$TLS_PORT_CONTAINER --name $CONTAINER_NAME $IMAGE_NAME

#run in background
docker run --restart always -d -h $SERVER_LOCAL --cap-add SYSLOG --privileged -v /var/logs:/var/log -p $TLS_PORT_HOST:$TLS_PORT_CONTAINER --name $CONTAINER_NAME $IMAGE_NAME

#cron
docker build --build-arg ALPINE_VERSION=$ALPINE_VERSION -t $CRON_IMAGE_NAME .
docker run -it --rm -h $CRON_LOCAL --privileged -v /var/logs/agentlogs-tls/:/var/log/agentlogs-tls/ --name $CRON_CONTAINER_NAME $CRON_IMAGE_NAME
docker run -it -d -h cron-docker --privileged -v /var/logs/agentlogs-tls/:/var/log/agentlogs-tls/ --name $CRON_CONTAINER_NAME $CRON_IMAGE_NAME

Docker Compose:

docker-compose -f ./docker-compose-dev.yml build

docker-compose -f ./docker-compose-prod.yml up -d
docker-compose -f ./docker-compose-prod.yml stop

2: Using existing certificates:

The variable file <.env> must be modified depending on the environment (#CA, #Server, #General blocks, #Existing certificates)

Load ENV

export $(cat .env | egrep -v "(^#.*|^$)" | xargs)

Copy certificates:

Certificates (CA.pem, certificate and server key) must be copied to the directory '.\rsyslog-ssl\rsyslog\certificates'

Change Docker configuration:

./generate-config-exists-crt.sh

Copy certificates to local folder (in case of using VOLUME '/etc/pki/rsyslog/'):

/etc/pki/rsyslog-docker/ #on HOST machine

Docker:

docker container stop $CONTAINER_NAME 
docker build --build-arg PATH_CONFIG=/config/ --build-arg PATH_CERT=/certificates/ -t $IMAGE_NAME .

#run
docker run -it --rm -h $SERVER_LOCAL --privileged --name $CONTAINER_NAME dev-syslog-tls
docker run -it --rm -h $SERVER_LOCAL --cap-add SYSLOG --privileged -v /var/logs:/var/log -p $TLS_PORT_HOST:$TLS_PORT_CONTAINER --name $CONTAINER_NAME $IMAGE_NAME

#run in background
docker run --restart always -d -h $SERVER_LOCAL --cap-add SYSLOG --privileged -v /var/logs:/var/log -p $TLS_PORT_HOST:$TLS_PORT_CONTAINER --name $CONTAINER_NAME $IMAGE_NAME

Docker Compose:

docker-compose -f ./docker-compose-dev.yml build

docker-compose -f ./docker-compose-prod.yml up -d
docker-compose -f ./docker-compose-prod.yml stop

Export VARS

export $(cat .env | egrep -v "(^#.*|^$)" | xargs)

Delete old containers (if exists):

docker container stop rsyslog-tls

Docker:

docker build --build-arg PATH_CONFIG=/config/ --build-arg PATH_CERT=/certificates/ -t $IMAGE_NAME .

#run
docker run -it --rm -h $SERVER_LOCAL --privileged --name $CONTAINER_NAME dev-syslog-tls
docker run -it --rm -h $SERVER_LOCAL --cap-add SYSLOG --privileged -v /var/logs:/var/log -p 10514:10514 --name $CONTAINER_NAME $IMAGE_NAME

#background
docker run --restart always -d -h $SERVER_LOCAL --cap-add SYSLOG --privileged -v /var/logs:/var/log -p 10514:10514 --name $CONTAINER_NAME $IMAGE_NAME

Docker Compose:

docker-compose build --build-arg PATH_CONFIG=/config/ --build-arg PATH_CERT=/certificates/
docker-compose up -d
docker-compose stop
