Docker & Tigrisfs

Hello,

I set up tigrisfs locally, and now I’m trying to set it up in a Docker container on Render. However, I’m running into issues. I managed to get as far as here with a Dockerfile and start.sh:

FROM python:3.11-slim-bookworm

WORKDIR /app

COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt

RUN playwright install-deps
RUN playwright install

RUN apt-get update && \
    apt-get install -y automake autotools-dev g++ git libcurl4-gnutls-dev libfuse-dev && \
    apt-get install -y wget tar curl jq rclone s3fs mailcap fuse3 gvfs-fuse && \
    wget https://github.com/tigrisdata/tigrisfs/releases/download/v1.2.1/tigrisfs_1.2.1_linux_amd64.tar.gz -O /app/tigrisfs.tar.gz && \
    tar -xzf /app/tigrisfs.tar.gz && \
    apt-get clean

COPY . .

RUN mkdir -p /app/vol
#RUN /app/tigrisfs test /app/vol
RUN ls -lA /app # C
RUN chmod +x /app/start.sh
RUN chmod +x /app/tigrisfs

#ENTRYPOINT ["/app/tigrisfs"]
ENTRYPOINT ["/app/start.sh"]
#CMD ["timeout", "15m", "python3", "app.py"]
CMD ["test", "/app/vol"]

#!/bin/bash

# 1. Check if the mount directory exists and is a directory
if [ ! -d "$2" ]; then
    echo "Mount directory $2 does not exist."
    exit 1
fi

# 2. Start TigrisFS mount in the BACKGROUND (&)
# This uses the arguments passed to the script: $1 (bucket) and $2 (mount point)
echo "Starting TigrisFS mount for $1 at $2..."
/app/tigrisfs --debug --debug_fuse --debug_s3 "$1" "$2" &

# 4. Wait for the mount to stabilize (Optional but safer for FUSE)
sleep 5
ls
df -h

# 5. Start your main Python application in the FOREGROUND
# This command will block, keeping the container running.
echo "Mount established. Starting Python script..."
python /app/app.py

# 7. Exit with the Python script's exit code
exit $?

However, the bucket is still not mounting (as seen by the output of df -h), and app.py cannot read the text file. Does anyone know what I’m missing to make this work?

Solution

Hi,

Try to add -f to the tigrisfs mount command, so logs are dumped to the terminal; this would give more information why it’s not mounted.

My guess is that access keys are not set up in the container.

Hi, thanks for the reply. Sorry, I missed it until now. I added what you suggested and got this back which seems to suggest nothing is wrong, but it still isn’t mounting. The access keys are getting set up correctly.

Actually, it’s now working. All I needed to do was give it more time to mount, so I changed “sleep 5” to “sleep 30” and eventually to “sleep 10".
