Release Docker builds of TimescaleDB
TimescaleDB is an open-source database designed to make SQL scalable for time-series data. For more information, see the Timescale website.
This image is based on the official Postgres docker image so the documentation for that image also applies here, including the environment variables one can set, extensibility, etc.
$ docker run -d --name some-timescaledb -p 5432:5432 timescale/timescaledb
Then connect with an app or the
$ docker run -it --net=host --rm timescale/timescaledb psql -h localhost -U postgres
You can also connect your app via port
5432on the host machine.
If you are running your docker image for the first time, you can also set an environmental variable,
TIMESCALEDB_TELEMETRY, to set the level of telemetry in the Timescale docker instance. For example, to turn off telemetry, run:
$ docker run -d --name some-timescaledb -p 5432:5432 --env TIMESCALEDB_TELEMETRY=off timescale/timescaledb
Note that if the cluster has previously been initialized, you should not use this environment variable to set the level of telemetry. Instead, follow the instructions in our docs to disable telemetry once a cluster is running.
timescaledb-tuneautomatically on container initialization. By default,
timescaledb-tuneuses system calls to retrieve an instance's available CPU and memory. In docker images, these system calls reflect the available resources on the host. For cases where a container is allocated all available resources on a host, this is fine. But many use cases involve limiting the amount of resources a container (or the docker daemon) can have on the host. Therefore, this image looks in the cgroups metadata to determine the docker-defined limit sizes then passes those values to
To specify your own limits, use the
TS_TUNE_NUM_CPUSenvironment variables at runtime:
$ docker run -d --name timescaledb -p 5432:5432 -e POSTGRES_PASSWORD=password -e TS_TUNE_MEMORY=4GB -e TS_TUNE_NUM_CPUS=4 timescale/timescaledb:latest-pg11
To not run
timescaledb-tuneat all, use the
$ docker run -d --name timescaledb -p 5432:5432 -e POSTGRES_PASSWORD=password -e NO_TS_TUNE=true timescale/timescaledb:latest-pg11
