loads the standard dependencies and configures JULEA using Meson and Ninja. By default JULEA files are copied to **/julea**. + +The Dockerfiles can be modified to create a new image.

In the same folder a script is created to configure the server. +The script loads the environment variables, sets the configuration of JULEA and starts a server. +Also, it adds the execution of the environment script to **.bashrc** so that the variables are loaded when entering the container. +This need to be done otherwise the JULEA commands are not available within the container. + +In the Dockerfile the script is copied into the image. The default port for ther JULEA server is exposed. +At the end the *ENTRYPOINT* is defined which calls the script when *docker run* is executed. +The default values for the script are provided by the *CMD* command (hostname: **juleaServer**, port number: **9876**). + +``` +cd ./container/docker/server +sudo docker build -t julea-server-image . +sudo docker run -it -d --name julea-server julea-server-image +sudo docker exec -ti julea-server /bin/bash +``` + +If the default values should be overwritten add the requested values at the end of the statement. + +``` +sudo docker run -it -d --name julea-server julea-server-image SERVERNAME PORT +``` + +For network communication, the hostname and port number given in the script must be set.

Here, the hostname and port number of the JULEA server are specified in the *CMD* command of the Dockerfile. If the default values are overwritten, this must happen in the client as well. +In the script a *tail* command is executed at the end, which ensures that the container is not shut down immediately after starting. +This would normally happen because no permanent process is running. + +``` +cd ./container/docker/client +sudo docker build -t julea-client-image . +sudo docker run -it -d --name julea-client julea-client-image +sudo docker exec -ti julea-client /bin/bash +``` + +If the default values should be overwritten: +``` +sudo docker run -it -d --name julea-client julea-client-image SERVERNAME PORT +``` + +To be able to communicate with the server, the network must also be specified. +``` +sudo docker run -it -d --network myNet --name julea-client julea-client-image +``` + +### Why to a script in ENTRYPOINT +The server's Dockerfile only contains the *ENTRYPOINT* that refers to a script. +Within the script the configuration for JULEA is done and a server is started. +The configuration is not set directly in the Dockerfile because every *RUN* command in the Dockerfile creates its own layer. +The environment variables, which are set by the environment script, are not persistent. +This means that another layer can't access them, which leads to the fact, +that with two *RUN* statements the command *julea-config* is no longer available and an error occurs. + +To do the whole configuration inside the Dockerfile becomes much too complicated and unclear. +Therefore it is recommended to outsource the configuration to an external script. + +### Volume +To be able to develop more dynamically, there is the possibility to mount local directories into the container. +So you could develop or use JULEA on the local host and then compile and execute the result in the container. + +``` +sudo docker run -it -d --network myNet -v /absolute/path/to/dir/build:/build --name julea-client julea-client-image +``` + +### Docker-Compose +To simplify the administration of containers there is a docker-compose example in the root directory of JULEA. +In this example a server and a client is created. The name of the service of juleaServer is the server name, +which must be set for the client, otherwise the server cannot be reached from the client. +For the server the ports are defined, which are visible to the hostsystem and other containers. +In addition, a name for the image and one for the container for both services is defined, so that no random ones are generated and remain unique. +For the client, a directory is mounted from the host into the container. + +Creating the network is no longer necessary, because docker-compose does this. For this example a network is created, +which is called *julea_default*. This can be examined with *docker network inspect julea_default*. + +To start both containers, just type: +``` +docker-compose up -d +``` + +## Singularity +No root privileges are required on the system. + +Logs can be found here: ~/.singularity/instances/logs/HOSTNAME/USERNAME/ + +## Singularity Image +All commands (exec, run and shell) use the image as read-only. +To use Singularity with JULEA, e.g. to compile files in the image, a directory with the files can be mounted to the container. + +In addition, by default some directories from the host system are mounted into the image. Read about this here: +https://sylabs.io/guides/3.7/user-guide/bind_paths_and_mounts.html?highlight=bind%20path + +The Singularity file uses the Docker images from the GitHub Container Registry. + +### Server +The Singularity server image copies a script into the image, which is executed when the instance is started. +This script sets the configuration for JULEA. The path for the backends is set here to the mounted directory. +Then the server is started with the hostname *juleaserver* and the port *9876*. +``` +cd ./container/singularity/server +singularity build --fakeroot julea-server.sif Singularity +singularity instance start --bind singularity-mnt/:/singularity-mnt julea-server.sif julea-server-instance +``` + +For the client, or other system, the IP address of the server is needed. This can be found out as follows. +The IP should be in subnet 10.X.X.X. +``` +singularity exec instance://julea-server-instance hostname -I +``` + +### Client +The Singularity client image proceeds the same way as the server image. +Again, a script is created that uses the hostname and port of the server. +In order to resolve the hostname of the server, the following step must be executed. +Alternatively you can also work with the IP address of the server, then this step is not necessary. + +Create an *etc.hosts* file in the directory of the client. +Add the IP address of the server and mount this file into the instance. +``` +cd ./container/singularity/client +singularity build --fakeroot julea-client.sif Singularity +singularity instance start --bind etc.hosts/:/etc/hosts --bind singularity-mnt/:/singularity-mnt julea-client.sif julea-client-instance +singularity shell instance://julea-client-instance +``` + +If you want to work with JULEA in the container, make sure that the environment variables are loaded. +``` +. /julea/scripts/environment.sh +``` + +## Podman +The Docker images and Dockerfiles are also supported by Podman. +Here you can use the same commands as for Docker. +Just replace *docker* with *podman* at the beginning of the instruction. + +### Podman-Compose +To use the *docker-compose.yml* with Podman, the following project can be used: https://github.com/containers/podman-compose diff --git a/docker-compose.yml b/docker-compose.yml new file mode 100644 index 000000000..dc517cb3d --- /dev/null +++ b/docker-compose.yml @@ -0,0 +1,15 @@ +services: + juleaServer: + build: + context: ./container/docker/server + ports: + - "9876:9876" + image: julea-server-image + container_name: julea-server + juleaClient: + build: + context: ./container/docker/client + volumes: + - "./example:/build" + image: julea-client-image + container_name: julea-client
