Pull request overview

Updates the InfluxDB 2.8 container images to remove gosu/su-exec and switch to setpriv for dropping root privileges, while changing how dasel is provided (built during image build rather than downloaded as a release artifact).

Changes:

• Replace gosu/su-exec with setpriv in both Debian and Alpine entrypoints.
• Add setpriv runtime dependencies (util-linux on Debian, setpriv package on Alpine) and remove the gosu install block.
• Build and copy dasel via a Go builder stage instead of downloading + SHA256-verifying release binaries.

influxdb/2.8/alpine/Dockerfile:23

• The previous dasel install step included a build-time smoke test (dasel --version). With the new COPY --from=dasel-builder approach, consider adding a simple version/executable check after the COPY so broken builder outputs are caught during image build rather than at runtime.

# Install dasel for configuration parsing, built with a current Go toolchain.
COPY --from=dasel-builder /go/bin/dasel /usr/local/bin/dasel

RUN addgroup -S -g 1000 influxdb && \
    adduser -S -G influxdb -u 1000 -h /home/influxdb -s /bin/sh influxdb && \
    mkdir -p /home/influxdb && \
    chown -R influxdb:influxdb /home/influxdb
