Use the Flux REPL (Read–Eval–Print Loop) to execute Flux scripts and interact with InfluxDB and other data sources. Build the REPL from the Flux source code.
{{% note %}} Flux REPL supports running Flux scripts against InfluxDB 1.8+. {{% /note %}}
To use the Flux REPL, build it from source using the Flux repository. For instructions, see the Flux repository README.
To open a new REPL session, run:
./flux repl
To query data from InfluxDB (local or remote), provide the host, organization, and token parameters
to the from() function.
from(
bucket: "example-bucket",
host: "http://localhost:8086",
org: "example-org",
token: "My5uP3rS3cRetT0k3n",
)
Multi-line scripts like the example above work when pasted into the REPL. Pasting newlines from the clipboard is allowed. However, you cannot enter newline characters directly from the keyboard.
Exit the REPL by pressing Control + D.
