日志文件生成在/tmp目录下，还是/home/egress/tmp目录下，因为我看日志中打印了/home/egress/tmp

Hi there! Just to help us get to the bottom of this, could you please confirm if you've customized the temporary directory path in your Egress service configuration? Usually, the log file is created in the system's temporary directory (like

/tmp

), but if you've set up a custom path such as

/home/egress/tmp

, it might be different. Thanks so much for checking!

怎么自定义生成路径，给出示例

To help you customize the directory where the Chrome log file is generated, you can simply set the

TMPDIR

environment variable to the path you prefer before starting the Egress service. Here’s an example to guide you:

TMPDIR=/path/to/your/custom/temp/dir docker run --rm \
    -e EGRESS_CONFIG_FILE=/out/config.yaml \
    -v ~/egress-test:/out \
    livekit/egress

This way, the Egress service will use the directory you specified for temporary files, including the Chrome log file. If you have any questions or need further assistance, feel free to ask—I’m here to help! Sources: pkg/config/output_segment.go

I'm sorry to hear you're encountering the "chrome failed to start" error in LiveKit Egress version 1.10. This usually happens because some system capabilities needed for Chrome to start properly are missing. Let's work through this together to get it sorted out: 1. Include the required Docker capability: Please add

--cap-add=SYS_ADMIN

to your

docker run

command. Here's an example to guide you:

docker run --rm \
      --cap-add SYS_ADMIN \
      -e EGRESS_CONFIG_FILE=/out/config.yaml \
      -v ~/livekit-egress:/out \
      livekit/egress

2. Check Chrome sandboxing settings: If your configuration has

enable_chrome_sandbox: true

, you'll also want to include

--security-opt seccomp=chrome-sandboxing-seccomp-profile.json

in your

docker run

command. This helps Chrome get the system calls it needs for sandboxing. 3. Optional for local testing: If sandboxing isn't necessary for your current setup, you can disable it by setting

enable_chrome_sandbox: false

in your configuration. Just a heads-up, this isn’t recommended for production environments. Give these steps a try, and if you’re still running into issues, please don’t hesitate to reach out. I’m here to help you get this resolved! Sources: Self-hosting the Egress Service | LiveKit Docs | pkg/pipeline/watch.go | Getting Help | livekit/livekit_composite | DeepWiki

enable_chrome_sandbox是false，仍然启动失败

Since

enable_chrome_sandbox

is set to

false

and Chrome still fails to start, let's work through a few steps together to get this sorted out: 1. Ensure SYS_ADMIN capability: Please check that your Docker container is launched with the

--cap-add=SYS_ADMIN

flag. Here's an example to guide you:

docker run --rm \
      --cap-add SYS_ADMIN \
      -e EGRESS_CONFIG_FILE=/out/config.yaml \
      -v ~/livekit-egress:/out \
      livekit/egress

2. Verify resource allocation: Make sure your container has at least 4 CPUs and 4 GB of memory allocated. This helps handle the resource-intensive tasks smoothly. 3. Enable Chrome logging: It’s helpful to set

debug.enable_chrome_logging: true

in your configuration. This will create a

chrome.log

file, which can give us more insight into what’s happening during Chrome’s startup. 4. Check configuration and dependencies: Let’s confirm a few things: ◦ The

ws_url

is pointing to a reachable LiveKit server. ◦ Redis is accessible from inside the container. ◦ If you’re not using Docker, ensure system dependencies like

xvfb

and

pulseaudio

are installed and available. Following these steps should help resolve the issue. If you’re still facing difficulties, please don’t hesitate to reach out—I’m here to help you get this working smoothly! Sources: test/edge.go | Self-hosting the Egress Service | LiveKit Docs

使用了官方的egress镜像部署的，会启动chrome失败吗

I'm here to help you with this! Even when using the official LiveKit Egress Docker image, Chrome might sometimes have trouble starting under certain conditions. Let’s walk through some of the most common reasons together: 1. Missing SYS_ADMIN capability: It’s important to launch the Docker container with the

--cap-add=SYS_ADMIN

flag. This is especially necessary since Chrome sandboxing is enabled by default starting from Egress v1.7.6. 2. Incorrect sandboxing configuration: If your configuration has

enable_chrome_sandbox: true

, you’ll also want to include

--security-opt seccomp=chrome-sandboxing-seccomp-profile.json

in your

docker run

command. This helps Chrome get the system calls it needs to set up the sandbox properly. 3. Resource or dependency issues: Make sure your container has enough resources — at least 4 CPUs and 4 GB of memory — and that dependencies like

xvfb

and

pulseaudio

are running smoothly. These hiccups can happen even with the official image if the Docker environment isn’t set up just right.

Let's work together to figure out why Chrome didn't start as expected. You can enable Chrome logging in your Egress configuration by setting

debug.enable_chrome_logging: true

. This will create a

chrome.log

file in the temporary directory, which contains detailed Chrome console and exception messages. Taking a look at this log file alongside the Egress service logs usually helps pinpoint the exact reason for the failure. Often, it could be due to missing Docker capabilities (like

--cap-add=SYS_ADMIN

) or resource limitations. Please feel free to reach out if you'd like any help going through the logs—I’m here to support you! Sources: pkg/pipeline/watch.go | Self-hosting the Egress Service | LiveKit Docs

chrome启动失败，配置

debug.enable_chrome_logging: true也会有日志记录吗

Setting

debug.enable_chrome_logging: true

will create a

chrome.log

file, which is great for capturing logs—but it will only have content if Chrome starts up successfully. If Chrome doesn’t start, the log file won’t show any console events or errors since the logging depends on Chrome being up and running and navigating to the specified URL. If you’re experiencing issues with Chrome not starting, it’s best to check the Egress service logs or make sure that the necessary Docker capabilities and configurations are correctly set.

I'm here to help you troubleshoot the "chrome failed to start" error when you see the message "internal error, shutting down." Let's walk through some steps together to get this sorted out: 1. Ensure SYS_ADMIN capability: Try adding

--cap-add=SYS_ADMIN

to your Docker run command. For example:

docker run --rm \
      --cap-add SYS_ADMIN \
      -e EGRESS_CONFIG_FILE=/out/config.yaml \
      -v ~/egress-test:/out \
      livekit/egress

This often helps Chrome start properly. 2. Check sandboxing configuration: If your configuration has

enable_chrome_sandbox

set to

true

, make sure to include

--security-opt seccomp=chrome-sandboxing-seccomp-profile.json

in your Docker command. If you don’t need sandboxing, it’s a good idea to explicitly set

enable_chrome_sandbox: false

to avoid any conflicts. 3. Enable Chrome logging: It’s super helpful to set

debug.enable_chrome_logging: true

in your configuration. This will create a

chrome.log

file that captures detailed Chrome console output, making it easier to spot what’s going wrong. 4. Verify system resources: Please check that your container has at least 4 CPUs and 4 GB of memory allocated. Sometimes, insufficient resources can cause Chrome to fail to start. 5. Check dependencies: If sandboxing is enabled, confirm that necessary system calls like

clone

and

unshare

are allowed by the Docker seccomp profile. This can prevent unexpected shutdowns. Following these steps usually helps identify or fix the issue. If you’re still having trouble, don’t hesitate to share the

chrome.log

file or any other logs you have. I’m here to help you get this working smoothly! Sources: Self-hosting the Egress Service | LiveKit Docs | test/edge.go

给出chrome启动命令，在arm服务器上面直接测试chrome

Let's try testing Chrome startup on your ARM server by running Chrome directly inside the Egress container. Here’s a simple way to do it: 1. First, access the running Egress container:

docker exec -it <egress-container-id> /bin/bash

2. Then, launch Chrome with minimal flags: `google-chrome --headless=new --disable-gpu --no-sandbox --dump-dom https://example.com`This will help us check if Chrome can start in headless mode and render a basic webpage. Just a quick reminder: make sure your Docker container is started with

--cap-add=SYS_ADMIN

to satisfy Chrome’s sandboxing needs. If you find that Chrome isn’t installed inside the container, you might want to install it or double-check the Egress image setup.
