Some scripts to create and run a Docker container with Projector and IDE.
For more info, please check out Projector.md.
Run IntelliJ IDEA in Docker
How to run IntelliJ IDEA Community in Docker and access it via a web browser?
Please check your Docker version: since we use Docker BuildKit in our scripts, a current version of Docker (18.09 or higher) is required.
projector-docker repo and make the following actions:
./clone-projector-core.sh ./build-container.sh ./run-container.sh
This will run nginx and Projector Server with IntelliJ IDEA Community locally.
To access Projector Server with IDE, use http://localhost:8080/projector/.
There will be a sample Kotlin + Java project opened, just close some dialogs. If you want to try your project, you can clone it via Git.
If you don't want to clone the project every time you start the container, go further: use
Accessing IDE run on another machine
If you want to access IDE run on another host, you need to change page parameters. Here are the default parameters, so you probably need to change
localhost in both places to needed IP: http://localhost:8080/projector/?host=localhost&port=8887.
Clones projector projects from Git to proper locations:
Note: if you already have these projects locally existing, you can place them to proper locations and avoid this script.
build-container.sh [containerName] [ideDownloadUrl]
Builds a Docker container locally.
build-container-dev.sh [containerName] [ideDownloadUrl]
Compiles and builds a Docker container locally. The script assumes the JAVA_HOME is set to a JDK 11.
create-image.sh [containerName] [tarGzFileName]
Creates a Docker image from a built container and saves it as a
Loads the Docker image locally.
Runs the Docker container.
Starts the server on port 8887.
Runs the Docker container. Also, it mounts your
~/projector-docker dir as the home dir in the container, so settings and projects can be saved between launches.
Feel free to change
~/projector-docker dir to your desired one. Please note that the host dir should be created manually to eliminate permissions problems.
For Mac and Windows hosts: to speed up work with mounted dirs, you can try adding the
:cached suffix. It will look like this:
Starts the server on port 8887.
When you build a container, there is an optional
ideDownloadUrl parameter, so you can select different IDEs to use. Most JetBrains IDEs of versions 2019.1-2020.2 will work. Tested with:
If you want to try other distribution, click "Other versions" on an IDE download page and copy a link to a
tar.gz file. Please ensure that you select
tar.gz with JBR, not without.
Q: Can I somehow secure my connection?
A: You can enable SSL for connection. First of all, provide the
ORG_JETBRAINS_PROJECTOR_SERVER_SSL_PROPERTIES_PATH environment variable on the server-side using the
-e parameter of
docker run. It should contain a path to a file with properties: you can place the file to a mounted dir. Example of such a file:
STORE_TYPE=JKS FILE_PATH=/path-to/keystore.jks STORE_PASSWORD=mypassword KEY_PASSWORD=mypassword
If you do everything right, the server launch log will contain something like
WebSocket SSL is enabled: /path-to/properties.file. If it logs
WebSocket SSL is disabled instead, something is wrong. Maybe the env variable can’t be found or there is an exception parsing the properties file (it will be logged).
After that, enable it on the client-side by adding the
wss query parameter like this: http://localhost:8080/projector/?wss. Make sure that your browser trusts the certificate you use.
Q: Can I assign a connection password?
A: Yes, you can set a password that will be validated on connection start on the server. There are two variants of access: full (read/write) when you can control UI via mouse and keyboard and read-only when you can only watch.
On the server-side, provide the
ORG_JETBRAINS_PROJECTOR_SERVER_HANDSHAKE_TOKEN environment variable containing the password for full access and the
ORG_JETBRAINS_PROJECTOR_SERVER_RO_HANDSHAKE_TOKEN environment variable for read-only access. On the client-side, you can specify the password in query parameters like this: http://localhost:8080/projector/?token=mySecretPassword. If you don't set passwords, by default they are equal to
null. If rw and ro passwords are the same, the server gives full access to clients with a correct password.
Q: I’ve mounted the home dir in Docker container and it seems that I can’t edit files, there are exceptions about permissions and missing files. What to do?
A: It can happen when the owner of the directory on the host is root. So you should recreate the directory on the host yourself with normal user permissions.
