Docker golang + ffmpeg fails to execute command

Question content

Hello, I am using the following docker image:

from golang:alpine3.18

Using ffmpeg: (Maybe I'm missing something here)

run apk add --no-cache ffmpeg

But when trying to do the following:

cmd := "ffmpeg -i untitled.mp4 -vf \"fps=5,scale=320:-1:flags=lanczos\" -c:v pam -f image2pipe - | convert -delay 5 - -loop 0 -layers optimize test.gif"
_, err := exec.command("bash", "-c", cmd).output()
if err != nil {
    fmt.println(fmt.sprintf("failed to execute command: %s", err))
}

I get this error:

Failed to execute command: exec: "bash": executable file not found in $PATH

Correct answer

The Alpine docker image does not have bash installed by default. It uses Ash shell instead

The answer is already here Docker: How to use bash with Alpine based docker image?
