QUESTION
I am having this weird issue with elastic beanstalk. I am using docker compose to run multiple docker containers on same elastic beanstalk instance.
if I run 4 docker containers everything works fine. but if i make it 5, deploy fails with error Instance deployment failed to download the Docker image. The deployment failed
.
and if I check eb-engine.log. it retries to docker pull
command and fails with error.
this is really weird error. bcs all docker images are valid and correctly tagged. it just the number of services that I am adding in docker compose file. if number is greater than 4, deploy fails
my question is, is there any limit of docker services that can be run using docker compose ? or is there any timeout in elastic beanstalk to pull images?
...ANSWER
Answered 2021-Jun-16 at 03:01Based on the comments.
The issue was that t2.micro
instance was used. The instance has only 1 vCPu and 1GB of ram. This was not enough to run 5 docker containers. Changing instance type to t2.large
with 8GB ram and 2 vCPUs solved the problem.
docker-compose allows to specify cpu and memory limits. Maybe you can set them up to keep your containers resource requirements in check.

Answered 2021-Jun-15 at 20:40From what it looks like, options is actually an array of objects rather than just an object. So all you would need to do is map over the options variable. You are currently using Object.keys which is what you use if you are wanting to iterate over the keys in an object.

I'm trying to docerize my NodeJS API together with a MySQL image. Before the initial run, I want to run Sequelize migrations and seeds to have the tables up and ready to be served.

ANSWER
Answered 2021-Jun-15 at 15:38I solved my issue by using Docker Compose Wait. Essentially, it adds a wait loop that samples the DB container, and only when it's up, runs migrations and seeds the DB.
My next problem was: those seeds ran every time the container was run - I solved that by instead running a script that runs the seeds, and touch
s a semaphore file. If the file exists already, it skips the seeds.

QUESTION
I'm currently trying out Android Compose. I have a Text that shows price of a crypto coin. If a price goes up the color of a text should be green, but if a price goes down it should be red. The function is called when a user clicks a button. The problem is that the function showPrice()
is called multiple times (sometimes just once, sometimes 2-4 times). And because of that the user can see the wrong color. What can I do to ensure that it's only called once?

Nothing, that's how it's meant to work. In the View system you would not ask "Why is my view invalidated 3 times?". The framework invalidates (recomposes) the view as it needs, you should not need to know or care when that happens.
The issue with your code is that your Composable is reading the old value from preferences, that is not how it should work, that value should be provided by the viewmodel as part of the state. Instead of providing just the new price, expose a Data Class that has both the new and old price and then use those 2 values in your composable to determine what color to show, or expose the price and the color to use.
