Install Docker:
On Goobuntu, we recommend overriding the default graph dir (/var/lib/docker) to avoid filling up the root filesystem partition, which is quite small. To do so, add the following line to your /etc/default/docker:
DOCKER_OPTS="${DOCKER_OPTS} -g /usr/local/google/docker"
Add your user to the docker group:
$ sudo usermod -a -G docker $(whoami)
Start (or restart) the Docker daemon:
$ sudo service docker restart
Build the playground Docker image (this will take a while...):
$ cp ~/.netrc $V23_ROOT/release/projects/playground/go/src/v.io/x/playground/netrc $ docker build -t playground $V23_ROOT/release/projects/playground/go/src/v.io/x/playground/.
Note: If you want to ensure an up-to-date version of Vanadium is installed in the Docker image, run the above command with the “--no-cache” flag.
Note: If you have only a .gitcookies googlesource.com entry and not a .netrc one, you can convert it to a .netrc entry using:
$ cat ~/.gitcookies | grep vanadium.googlesource.com | tail -n 1 | sed -E 's/(\S+)\s+(\S+\s+){5}([^=]+)=(\S+)/machine \1 login \3 password \4/' >> ~/.netrc
(see http://www.chromium.org/chromium-os/developer-guide/gerrit-guide for details)
The ‘docker build’ command above will compile builder from the main Vanadium repository. If you want to use local code instead, open Dockerfile and uncomment marked lines before running the command.
Test your image (without running compilerd):
$ $V23_ROOT/release/projects/playground/go/bin/pgadmin bundle make fortune js-go | docker run -i playground
Install the playground binaries:
$ GOPATH=$V23_ROOT/release/projects/playground/go v23 go install v.io/x/playground/...
Run the compilerd binary:
$ $V23_ROOT/release/projects/playground/go/bin/compilerd --listen-timeout=0 --address=localhost:8181 --origin='*'
Or, run it without Docker (for faster iterations during development):
$ PATH=$V23_ROOT/release/go/bin:$V23_ROOT/release/projects/playground/go/bin:$PATH compilerd --listen-timeout=0 --address=localhost:8181 --origin='*' --use-docker=false
The server should now be running at http://localhost:8181 and responding to compile requests at http://localhost:8181/compile.
Add ?pgaddr=http://localhost:8181 to any playground page on localhost to make the client talk to your server. Add ?debug=1 to see debug info from the builder.
NOTE: These instructions should only be used for local development and testing, and not for production deploys.
Install MariaDB:
$ sudo apt-get install mariadb-server
Sign in to Maria as root:
$ mysql -u root -p
Create playground databases:
MariaDB [(none)]> CREATE DATABASE IF NOT EXISTS pg_moria;
Create a playground user who has access to the playground database:
MariaDB [(none)]> GRANT ALL PRIVILEGES ON pg_moria.* TO 'pg_gandalf'@'localhost' IDENTIFIED BY 'mellon';
Create config/db.json from default:
$ cp config/db-local-default.json config/db.json
Alternatively, make your own from example.
The compilerd server can now be started with persistence enabled by:
$ make start
Make sure you have built a docker playground image, following the steps above.
Make sure that MariaDB is installed, following the steps above.
Run sql_test_setup.sh. You will be prompted for your MariaDB password for root account. You only need to do this once.
$ ./sql_test_setup.sh
This script will create a playground_test database, and a playground_test user that can access it.
Run the tests:
$ GOPATH=$V23_ROOT/release/projects/playground/go v23 go test v.io/x/playground/compilerd/...
Migrations use the github.com/rubenv/sql-migrate library, wrapped in a tool pgadmin to allow TLS connections.
Create the database and config/db.json file following instructions above.
To migrate up, first run with -n (dry run):
$ $V23_ROOT/release/projects/playground/go/bin/pgadmin -sqlconf=./config/db.json migrate up -n
If everything looks good, run the same command without -n; alternatively, run:
$ make updatedb
You can undo the last migration with:
$ $V23_ROOT/release/projects/playground/go/bin/pgadmin -sqlconf=./config/db.json migrate down -limit=1
For more options and infomation, run:
$ $V23_ROOT/release/projects/playground/go/bin/pgadmin help
and see https://github.com/rubenv/sql-migrate
Migrations are kept in the migrations directory. They are ordered alphabetically, so please name each migration consecutively. Never delete or modify an existing migration. Only add new ones.
Each migration file must define an “up” section, which begins with the comment
-- +migrate Up
and a “down” section, which begins with the comment
-- +migrate Down
Applying a single migration “up” and then “down” should leave the database in the same state it was to begin with.
For more information on writing migrations, see https://github.com/rubenv/sql-migrate#writing-migrations
The playground client expects to find up-to-date default examples already present in the database to use as templates for editing. The unpacked example source code can be found in the bundles directory, described in bundles/config.json. Each example is obtained by filtering files from a folder according to a glob-like configuration and bundling them into a JSON object that the client can parse.
Bundling and loading the examples into a fresh database, as well as updating, is handled by the pgadmin tool:
$ $V23_ROOT/release/projects/playground/go/bin/pgadmin -sqlconf=./config/db.json bundle bootstrap
Or simply:
$ make bootstrap
When adding new default examples or implementations of existing ones, bundles/config.json must also be edited to include them in bootstrapping and tests. For config file format documentation, see:
$ $V23_ROOT/release/projects/playground/go/bin/pgadmin bundle help bootstrap
