Add InfluxDB module - #1445
Conversation
Supports the InfluxDB 2.x line (org/bucket/token setup) and the legacy 1.x line (database/user), choosing the flavour from the image tag. The started container exposes the URL and credentials so a client can connect straight away. Tests write points and read them back through the official influxdb-client on 2.x and over HTTP on 1.x. Picks up testcontainers#1130 and adds the docs that were missing.

Poem
Merge Risk: 🟡 Moderate · up to The module adds InfluxDB 1.x and 2.x support, but unsupported or rolling image tags such as latest can be treated as InfluxDB 2.x and fail to initialize when they point to InfluxDB 3, while the default 2.x authentication token is not exposed to callers. These are bounded but concrete compatibility and usability risks that should be fixed or explicitly accepted before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Make the extracted documentation examples self-contained.
The inside_block directives in docs/modules/influxdb.md emit only these marked regions. The 2.x example omits the imports and INFLUXDB2_IMAGE. The 1.x example omits the InfluxDBContainer import and INFLUXDB1_IMAGE. A reader cannot copy either example into a project without resolving undefined identifiers.
Include the required imports and a concrete image declaration in each documented block, or replace the codeinclude blocks with self-contained examples.

Official InfluxDB Docker image DOCKER_INFLUXDB_INIT_ADMIN_TOKEN omitted setup generates operator token behavior
💡 Result:
When using the official InfluxDB Docker image, if you omit the DOCKER_INFLUXDB_INIT_ADMIN_TOKEN environment variable (and do not provide a value via DOCKER_INFLUXDB_INIT_ADMIN_TOKEN_FILE), InfluxDB will automatically generate an initial Operator token during the setup process [1][2]. The behavior is as follows: 1. Automatic Generation: If no initial token is supplied during the initialization phase (triggered by setting DOCKER_INFLUXDB_INIT_MODE=setup), InfluxDB generates a secure, random Operator token for you [1][2]. 2. Storage: The system automatically stores this generated token in the active Influx CLI configuration, which allows the local CLI tool to authenticate and perform operations subsequently [2]. 3. Retrieval: If the token is auto-generated, it is not explicitly printed in the container logs for security reasons. Users who need to retrieve or verify this token after the fact can check the generated Influx CLI config files within the container, or use the influxd recovery tools if they lose access to their initial credentials [2]. The DOCKER_INFLUXDB_INIT_ADMIN_TOKEN_FILE environment variable exists as an alternative mechanism to provide this token securely via Docker secrets or mounted files [1][3][4]. If you specify this variable but the file does not exist, the entrypoint script will issue a warning and skip the file, effectively behaving as if no token was provided, unless a default value is supplied through other means [5][6].

Expose a usable default InfluxDB 2.x token.
When withAdminToken() is not called, the 2.x setup omits DOCKER_INFLUXDB_INIT_ADMIN_TOKEN. InfluxDB generates a token, but getAdminToken() returns undefined because the class does not retrieve it. Set a deterministic default token or expose the generated token after startup.

InfluxData GitHub issue 27135 influxdb latest September 15 2026 InfluxDB 3 Core port 8181
💡 Result:
As of August 27, 2026, InfluxData has announced a breaking change regarding the Docker latest tag for the InfluxDB image, as tracked in GitHub issue #27135 [1][2]. On Tuesday, September 15, 2026, the latest tag for the official InfluxDB Docker image will change from pointing to InfluxDB 2 to pointing to InfluxDB 3 Core [1][3]. Users who rely on the latest tag to retrieve updates will experience an upgrade to InfluxDB 3 Core the next time they pull the image after this date, which may break existing deployments [1][4]. To avoid an unexpected upgrade, InfluxData recommends updating Docker deployments to use a specific version tag, such as docker pull influxdb:2 [1][3][4]. Regarding port 8181, it is the default port for the HTTP API in InfluxDB 3 Core [5][3]. Documentation for setting up InfluxDB 3 Core in Docker explicitly includes mapping this port (e.g., -p 8181:8181) [6][7][3]. The default configuration listens on 0.0.0.0:8181 [6][7].

Reject unsupported image tags instead of treating them as InfluxDB 2.x.
isInfluxDB2(this.imageName.tag) classifies latest and all major versions >= 2 as InfluxDB 2.x. The container then applies InfluxDB 2.x settings and waits on port 8086. After influxdb:latest moves to InfluxDB 3 Core, this setup can fail because InfluxDB 3 Core uses a different setup model and defaults to port 8181.
Accept only explicit 1.x and 2.x tags. Throw for latest and unsupported major versions.
