h1. Docker Upgrade - Ubuntu 22-04

h2. New docker container

It is recommended to create a new docker container with the new typo3 docker branch *ubuntu22* instead of upgrading an existing one. 

How to clone the specific branch:

<pre>

git clone -b ubuntu22 https://git.math.uzh.ch/typo3/typo3-docker.git

</pre>

h2. Upgrading existing docker

Manual to upgrade an existing docker container and setting up websocket server.

*Caution:* The used websocket port 8090 in this manual is only an example. Please use a port number which is not already used from others on the same server.

<pre>

1. At least Ubuntu 22.04 needs to be installed in docker container. (Usually done inside Dockerfile.nginx):

FROM ubuntu:22.04

1.1 Add the following to the top of your docker file (after FROM ubuntu:22.04) if it does not already exist. It defines the timezone configurations for the ubuntu 22.04 installation:

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update && \

    apt-get install -y tzdata && \

    ln -fs /usr/share/zoneinfo/Europe/Zurich /etc/localtime && \

    dpkg-reconfigure --frontend noninteractive tzdata

1.2(optional) If you are using wkhtmltopdf 0.12.6-1, you will need to manually install libssl1.1 in the docker file before wkhtmltopdf is installed. Reason: libssl1.1 is no longer included in Ubuntu 22.04:

# Manually install libssl1.1

RUN wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.0g-2ubuntu4_amd64.deb

RUN dpkg -i libssl1.1_1.1.0g-2ubuntu4_amd64.deb

2. Best practice is to expose the websocket port in the dockerfile (Dockerfile.nginx), it should be added before the services start, example: 

EXPOSE 8090

CMD service php8.1-fpm start && service ssh start && nginx

3. Add new websocket port (8090) to nginx webserver in Dockerfile, example:

  nginx:

    image: webserver

    build: 

      dockerfile: Dockerfile.nginx

    ports:

      - "46301:46301"

      - "51301:51301"

      - "44909:22"

      - "8090:8090"         <------ Websocket port

4. nginx config file adjustments, add following proxy:

	location /ws {

        proxy_pass http://mydomain:8090;

        proxy_http_version 1.1;

        proxy_set_header Upgrade $http_upgrade;

        proxy_set_header Connection "upgrade";

        proxy_set_header Host $host;

    }

5.(optional) If you upgrade your docker from an older version of ubuntu, your xdebug configuration may not work anymore. Adjustments are needed in the .ini file (99-math.ini), replace the existing xdebug configuration with this one:

# New xdebug 3 version:

xdebug.mode = debug

xdebug.start_with_request = yes

xdebug.client_port = 51301

xdebug.discover_client_host = 1

xdebug.max_nesting_level = 400

#xdebug.log=/var/log/apache2/xdebug.log

6. Start/Restart (Build first time) the docker container.

7. Set the configured websocket port and websocket url in QFQ Config, examples:

websocketPort: 8090

websocketUrl: ws://mydomain:46301/ws

8. If websocketPort is set in qfq config, the websocket server should start automatically the first time a web page with qfq content is loaded.

</pre>

9. If you are upgrading the qfq extension (new with FE Chat) in an already existing project, then you need to add the new enum value *chat* to the column *type* from the *FormElement* table.
