| 18 Introduction | |
| 19 ------------ | |
| 20 | |
| 21 `Docker images <https://en.wikipedia.org/wiki/Docker_(software)>`__ | |
| 22 for the Orthanc core and its official plugins are freely available on | |
| 23 the `DockerHub platform <https://hub.docker.com/u/jodogne/>`__. The | |
| 24 source code of the corresponding Docker images is available on `GitHub | |
| 25 <https://github.com/jodogne/OrthancDocker>`__. | |

| 1109 | 30 ``jodogne/orthanc`` vs. ``orthancteam/orthanc`` Docker images |
| 31 ------------------------------------------------------------- | |
| 1102 | 32 |
| 33 Two different flavors of Docker images for Orthanc are available: | |
| 229 | 34 |
| 1109 | 35 * The ``jodogne/orthanc`` and ``jodogne/orthanc-plugins`` Docker images that are |
| 36 described on this page are regularly kept in sync with the latest releases of | |
| 37 the Orthanc project, with a basic configuration system that is inherited from | |
| 38 the Debian packages (i.e., manual edition of the configuration files). | |
| 39 | |
| 40 This is also where the new experimental features from `Sébastien Jodogne's | |
| 41 research team at UCLouvain <https://orthanc.uclouvain.be/>`__ are initially | |
| 42 released. The binaries used in these images correspond to the Linux Standard | |
| 43 Base binaries. | |
| 44 | |
| 45 The default user interface is the built-in **Orthanc Explorer**. | |
| 46 | |
| 47 These images are most useful to **software developers and researchers**. | |

49 * Our commercial partner `Orthanc Team <https://orthanc.team/>`__ also |
| 1102 | 50 `publishes separate Docker images |
| 1109 | 51 <https://hub.docker.com/r/orthancteam/orthanc>`__. |
| 52 | |
| 53 These ``orthancteam/orthanc`` images are released 2 or 3 times a month every | |
| 54 time a new version of a plugin or Orthanc is available or every time the base | |
| 55 Debian image needs to be updated for security reasons. | |
| 56 | |
| 57 Each image has a tag and the `list of each component version is documented | |
| 58 <https://hub.docker.com/r/orthancteam/orthanc>`__. | |
| 59 | |
| 60 These images support both AMD64 and ARM64 architectures. | |
| 61 | |
| 62 These images can be configured using congirutation files or **environment | |
| 63 variables** (which is very handy if using Docker Compose or Kubernetes). | |
| 64 | |
| 65 The default user interface is the **Orthanc Explorer 2** :ref:`plugin | |
| 66 <orthanc-explorer-2>`. | |
| 67 | |
| 68 These images are targeted at **ops teams and end-users**. | |
| 69 | |
| 70 A :ref:`specific page <docker-orthancteam>` is available to describe how these | |
| 71 images should be used. | |
| 229 | 72 |
| 73 **Note for CentOS users:** The Docker environment might be difficult to | |
| 54 | 74 configure on your platform. Hints are available on the `Orthanc Users |
| 75 discussion group | |
| 76 <https://groups.google.com/d/msg/orthanc-users/w-uPAknnRQc/-XhzBGSCAwAJ>`__. | |
| 77 | |

| 79 Running the Orthanc core | |
| 80 ------------------------ | |
| 81 | |
| 82 The following command will start the core of Orthanc, with all the | |
| 83 plugins disabled:: | |

|
85 $ docker run -p 4242:4242 -p 8042:8042 --rm jodogne/orthanc |
| 54 | 86 |
| 87 Once Orthanc is running, use Mozilla Firefox at URL | |
| 88 http://localhost:8042/ to interact with Orthanc. The default username | |
| 89 is ``orthanc`` and its password is ``orthanc``. | |
| 90 | |
| 91 The command above starts the mainline version of Orthanc, whose | |
| 69 | 92 development is in continuous progress. Do not forget to regularly |
| 93 update the Docker image to benefit from the latest features:: | |

|
95 $ docker pull jodogne/orthanc |
| 69 | 96 |
| 97 If more stability is required, you can select the official release of | |
| 98 Orthanc to be run:: | |
| 54 | 99 |
| 1075 | 100 $ docker run -p 4242:4242 -p 8042:8042 --rm jodogne/orthanc:1.12.4 |
| 54 | 101 |
| 102 Passing additional command-line options (e.g. to make Orthanc verbose) | |
| 103 can be done as follows (note the ``/etc/orthanc`` option that is | |
| 104 required for Orthanc to find its configuration files):: | |
| 105 | |
| 1075 | 106 $ docker run -p 4242:4242 -p 8042:8042 --rm jodogne/orthanc:1.12.4 /etc/orthanc --verbose |
| 54 | 107 |
| 108 | |
| 109 Usage, with plugins enabled | |
| 110 --------------------------- | |
| 111 | |
| 112 The following command will run the mainline version of the Orthanc | |
| 113 core, together with its :ref:`Web viewer <webviewer>`, its | |
| 114 :ref:`PostgreSQL support <postgresql>`, its :ref:`DICOMweb | |
| 115 implementation <dicomweb>`, and its :ref:`whole-slide imaging viewer | |
| 116 <wsi>`:: | |

| 133 Fine-tuning the configuration | |
| 134 ----------------------------- | |
| 135 | |
| 136 For security reasons, you should at least protect your instance of | |
| 137 Orthanc by changing this default user, in the ``RegisteredUsers`` | |
| 138 :ref:`configuration option <configuration>`. You will also probably | |
| 139 need to fine-tune other parameters, notably the list of the DICOM | |
| 140 modalities Orthanc knows about. | |
| 141 | |
| 142 You can generate a custom configuration file for Orthanc as follows:: | |
| 143 | |
| 1075 | 144 $ docker run --rm --entrypoint=cat jodogne/orthanc:1.12.4 /etc/orthanc/orthanc.json > /tmp/orthanc.json |
| 54 | 145 |
| 146 Then, edit the just-generated file ``/tmp/orthanc.json`` and restart | |
| 147 Orthanc with your updated configuration:: | |
| 148 | |
| 1075 | 149 $ docker run -p 4242:4242 -p 8042:8042 --rm -v /tmp/orthanc.json:/etc/orthanc/orthanc.json:ro jodogne/orthanc:1.12.4 |

| 161 Configuration management using Docker Compose | |
| 162 --------------------------------------------- | |
| 163 | |
| 164 Depending on the context, the `Docker Compose tool | |
| 165 <https://docs.docker.com/compose/>`__ might be easier to use than the | |
| 166 plain Docker tool, as it allows replacing long command lines as above, | |
| 167 by plain configuration files. The trick here is to provide the JSON | |
| 168 configuration files to Orthanc as `secrets | |
| 169 <https://docs.docker.com/compose/compose-file/#secrets>`__ (note that | |
| 170 the related option ``configs`` could in theory be better, | |
| 171 unfortunately it is only available to `Docker Swarm | |
| 172 <https://github.com/docker/compose/issues/5110>`__). | |

| 54 | 222 Making the Orthanc database persistent |
| 223 -------------------------------------- | |
| 224 | |
| 225 The filesystem of Docker containers is volatile (its content is | |
| 226 deleted once the container stops). You can make the Orthanc database | |
| 227 persistent by mapping the ``/var/lib/orthanc/db`` folder of the | |
| 228 container to some path in the filesystem of your Linux host, e.g.:: | |
| 229 | |
| 230 $ mkdir /tmp/orthanc-db | |
| 1075 | 231 $ docker run -p 4242:4242 -p 8042:8042 --rm -v /tmp/orthanc-db/:/var/lib/orthanc/db/ jodogne/orthanc:1.12.4 |
| 54 | 232 |
| 233 | |
| 234 Whole-slide imaging support | |
| 235 --------------------------- | |
| 236 | |
| 237 The ``orthanc-plugins`` image includes support for :ref:`microscopic | |
| 238 whole-slide imaging (WSI) <wsi>`. For instance, the following command | |
| 239 will start the WSI viewer plugin transparently together with Orthanc:: | |
| 240 | |
| 1075 | 241 $ docker run -p 4242:4242 -p 8042:8042 --rm --name orthanc-wsi jodogne/orthanc-plugins:1.12.4 |
| 54 | 242 |
| 243 Note that we gave the name ``orthanc-wsi`` to this new Docker | |
| 244 container. Then, the Dicomizer command-line tool can be invoked as | |
| 245 follows:: | |
| 246 | |
| 1075 | 247 $ docker run -t -i --rm --link=orthanc-wsi:orthanc --entrypoint=OrthancWSIDicomizer -v /tmp/Source.tif:/tmp/Source.tif:ro jodogne/orthanc-plugins:1.12.4 --username=orthanc --password=orthanc --orthanc=http://orthanc:8042/ /tmp/Source.tif |
| 54 | 248 |
| 249 This command needs a few explanations: | |
| 250 | |
| 251 * ``--link=orthanc-wsi:orthanc`` links the container running the | |
| 252 Dicomizer, to the Docker container running Orthanc that we started | |
| 253 just before. | |
| 254 * ``--entrypoint=OrthancWSIDicomizer`` specifies that the Dicomizer | |
| 255 must be run instead of the Orthanc server. | |
| 256 * ``-v /tmp/Source.tif:/tmp/Source.tif:ro`` maps the source image | |
| 257 ``/tmp/Source.tif`` on the host computer into the Orthanc container | |
| 258 as read-only file ``/tmp/Source.tif``. | |
| 259 * ``--orthanc=http://orthanc:8042/`` instructs the Dicomizer to push | |
| 260 images through the ``--link`` created above. | |
| 261 * ``--username=orthanc --password=orthanc`` correspond to the default | |
| 262 credentials of the ``orthanc-plugins`` image. | |
| 263 | |
| 264 Obviously, you are free to add all the options you wish (check out the | |
| 265 ``--help`` flag to list these options). In particular, the | |
| 266 ``--dataset`` option allows to specify DICOM tags, in the JSON file | |
| 267 format, so as to include them in the resulting DICOM series (the | |
| 268 option ``--sample-dataset`` prints a sample JSON file that has the | |
| 269 expected format). | |
| 270 | |
| 271 If you have a source image that is not a hierarchical TIFF, you must | |
