How to sterilize large garden containers
You can sterilize by solarizing the soil same as you would a garden bed.
Can I use a canvas bag or burlap sack to grow vegetables in? I find that most fabric planters on the market are made with recycled plastic and not so eco friendly.
I'm sure you can! This article mentions growing potatoes in a burlap bag and I'm sure it works for other veggies:

You advertise a peach sorbet blueberry bush on Amazon. I am trying to find out the size of a #2 pot.
We wouldn't know specifics about any of the advertisers' products, but it should tell on their website what size plant you are getting. They can vary from vendor to vendor.

We do not sell plants. We only offer gardening information.
A #2 is a 2 gallon trade container.

You will use the correct soil based on the type of plant that you will be planting. This will differ based on the type of plant. Plants that prefer acidic soil will need an acidic blend. Plants that prefer things on the dry side will need cactus or orchid blends. Plants that do not tolerate large amounts of nitrogen in soil will need to be planted in a mix that is suitable, and not a synthetically fed soil.
Unfortunately, these factors depend on the types of plants that will be planted.
Generally, though, containers with a removable drain pan and plenty of drainage holes will be best. The size will depend on the plants in question.
Make sure that you are not using metals that rust, or otherwise interact with gasses and moisture. Make sure that your containers are PET or other food safe plastics.

I bought some plants from nursery in medium pots. I think that were in clay only. I made good fluffy potting mix but put plants directly in bigger pot with old clay bundle around roots. Should I removed old clay bundle around roots bcoz I am afraid that roots will stuck in old clay bundle and will not spread in excess area where I use good potting mix. Please advise should I do this or roots will find way to get out from old clay bundle which is in center of my pot. Thanks in advance
That is unfortunate! I would remove the clay, but you will want to do so in a specific way. This will ensure that you do not break the roots.
Soak the root ball in a bucket of water until the clay is able to be shaken off, gently. After, you can plant as you intend to.
What do I line it with it's plastic
There will be no need to line plastic containers. They are ready to go, as long as they are made for gardening. If you are concerned about the concrete getting dirty, you may want drip pans under your containers. This way you can safely remove all extra water from your containers without it spilling everywhere.
